See Research for more on upgrade mechanics, and Upgrade Tree for a list of upgradable appliances.
Blueprints allow players to purchase new Appliances, Ingredients, and Decorations for the restaurant using 
coins. These blueprints are provided at the start of each Preparation Phase, which the game refers to as the Shop. The amount provided is typically five, but may vary depending on the day, certain Cards, or Appliances.
Blueprints will appear as envelopes at the start of each Preparation Phase, and can be opened using Grab. Walking over a blueprint provides a full description of its corresponding item, which may be purchased by holding Interact.
Each blueprint displays icons depending on its properties.
This blueprint has been copied using a Copying Desk. It cannot be copied further, but may be upgraded, discounted, or rerolled.
This blueprint can be upgraded using a Research Desk.
This blueprint can be enchanted using a Enchanting Desk (from the Halloween 2023 event).- This blueprint can be purchased. If players have insufficient coins, this icon will be red.
Players can also Grab a blueprint and place it into a Blueprint Cabinet. Blueprints stored in this way are protected, since any left on the floor when leaving the Preparation Phase will be lost (if Practice Mode is activated, loose blueprints will disappear temporarily, but reappear upon exiting).
The type and quality of Blueprints available to players can be manipulated through upgrading, as well as with the Blueprint Desk and rerolls.
¶ Pools
Pools are the different item sets from which blueprints are randomly chosen for the shop, rerolls, and Blueprint Desk (the selection process for each is described in their respective sections below). Items may shift between pools over the course of the run, depending on the active Cards and appliances currently present in the restaurant.
The Blueprint's border are color-coded to indicate a category the blueprint belong in. Though there are 5 different colors, they can be divided into 2 main categories:
- Staples: Permanent Staple (white), Conditional Staple (yellow), Bonus Staple (neon-purple)
- Non-Staples: Base (blue), Upgraded (neon-blue)
¶ Staple Pool
| Permanent (white border) | Conditional (yellow border) | |||||

The Staple Pool consists of only Staple blueprints, and are the most common blueprints to be offered by the shop at the start of a new run, but become rarer the further a run goes. Items in the Staple Pool will NEVER be produced by a reroll.
The contents of this pool can change over the course of a run.
-
Conditional Staples (yellow border) only belong to the Staple Pool if no physical copies of the appliance are currently present in the restaurant. Once the appliance is purchased and placed, it becomes a Base appliance (blue border) and is moved to the Non-Staple Pool. If all physical copies of the appliance are ever removed from the restaurant, it will revert to a conditional staple (yellow border) and return to the Staple Pool.
(Since one Blueprint Cabinet is always present from Day 1, it starts in the Seed Pool on a new run).
-
Bonus Staples (neon-purple border) only appear when an items has been moved into the Staple Pool as a result of a
Franchise Cards and remain their for the entire run, and any future franchise runs with that Franchise Card.
¶ Seed Pool
The Seed Pool is determined by the current seed (may be referred to as the layout), and contains the non-staple items that are currently not part of the Non-droppable Pool. All blueprints for rerolls, and some for the shop, are chosen from this pool. As this pool contains a large variety of different items and will expand over the course of a run, it is possible certain items may not appear during a run by pure chance.
- Upgraded appliances (neon-blue border) has a 0% chance of appearing at the shop or through a reoll, but this increases by 10% after every 5 days completed. As there are no upgraded appliance that are also a staple appliance, the upgraded version of all the staple appliances are part of this pool, like a Danger Hob or Power Sink.
¶ Non-droppable Pool
The Non-droppable Pool mostly consists of Ingredients and Equipment not currently required by the restaurant.
Blueprints for Non-droppable items will never be produced by the shop, a reroll, or the Blueprint Desk until players choose a 
Food Card which requires new Ingredients or Equipment. At this point, the relevant items are transferred to the Seed Pool.
There are some exceptions to this rule.
- Supplies are transferred to the Seed Pool once a Table Consumable is present in the restaurant.
- Patties will always belong to the Non-droppable Pool.
- Fish Providers will never appear as blueprints, even with a relevant Recipe. They are instead acquired through the
Fish Selection Card.
¶ Shop
The Shop refers to the selection of blueprints which appear in envelopes at the start of the Preparation Phase. These are randomly chosen from predetermined item sets known as Pools, the contents of which change as players acquire certain items and Cards (see sections on individual pools for more).
On a typical day (all except Day 1 and decoration days)...
- 4 blueprints are chosen from the Staple Pool. This number decreases by 1 every fifth day, down to a minimum of 2.
- All other blueprints are chosen from the Seed Pool. The chance for a blueprint to be upgraded increases by 10% every fifth day, starting at 0%.
On a 
decoration day (Day 6 and every subsequent fifth day)...
- 8 blueprints are chosen from Decorations, either miscellaneous or matching the chosen theme.
- Additionally, 3 wallpapers and 3 sets of flooring are chosen (these are not blueprints and cannot be stored or rerolled).
On Day 1 (upon starting a new run) there is no usual shop, but players may still be offered...
- 1 Booking Desk blueprint (must be unlocked, and "Booking Desk as parcel" must be disabled in Options > Game).
- Any blueprints granted by Franchise Cards for free starting items (Bootstrapping, Grabber, Wash Basin).
Guaranteeing blueprints for the following day using the Blueprint Desk will override the usual formula. This makes it possible for non-decoration blueprints to appear in the shop on decoration days.
When replaying the same seed with the setting "Seed effects everything" or reloading the same day, the shop will always produce the same blueprints, provided that all other variables remain consistent. However, if any condition changes such as: blueprints are has been changed to either dropped inside or outside the restaurant, different items are transferred between the pools (like as a result of chosen Food Cards, or the presence or absence of Conditional Staples), the shop may produce different blueprints.
¶ Reroll
Rerolling allows players to exchange all blueprints (excluding those stored in Blueprint Cabinets) for a new, randomly chosen selection.
Reroll is activated by holding Interact on the dice outside the restaurant during the Preparation Phase. This initially costs 10 , and its cost increases by 10 with each activation for the remainder of the run.
Like the shop, blueprints produced by a reroll follow certain conditions.
- All blueprints are chosen from the Seed Pool. Staple and Non-droppable items will never appear.
- On a typical day, only non-decoration items (Appliances and Ingredients) will appear.
- On a decoration day, only Decorations will appear, either miscellaneous or matching the chosen theme.
- After every 5 days completed, there is a 10% increased chance for upgraded appliances to appear, starting at 0%. (As decorations do not have any upgraded items, the earliest a player can benefit from this will occur on day 7)
Players may add to the blueprints offered by the shop for that day by removing and placing down others from Blueprint Cabinets (including copies produced by a Copying Desk), allowing for much larger rerolls. Keeping blueprints sealed in their envelopes, or having players hold blueprints, will not prevent them from being rerolled.
¶ Blueprint Desk
Further information: Blueprint Desk
The Blueprint Desk allows players to guarantee that a single copy of the chosen blueprint will appear in the shop at the start of the following day.
Upon leaving Preparation Mode, each Blueprint Desk in the restaurant will begin to cycle at random intervals through blueprints for non-upgraded Appliances and Ingredients that do not currently belonging to the Non-droppable Pool.
Pressing Interact on a desk will display a green tick and lock in the current blueprint for the rest of the day. Any Blueprint Desks still active at closing time (when the bar at the top of the screen is full) will automatically lock in their current blueprint.
On a typical day, multiple Blueprint Desks can override the usual shop selection for all but 1 blueprint, which will always be chosen from the Staple Pool. Beyond this, the number of blueprints offered by the shop will increase to accommodate any additional blueprints locked in the previous day.
- Example 1 | 2 Blueprint Desks | Typical Day (shop normally offers 5 blueprints)
3 blueprints will be chosen as usual from the Staple and Seed Pools, and 2 will be those guaranteed by the desks, for a total of 5. - Example 2 | 10 Blueprint Desks | Typical Day (shop normally offers 5 blueprints)
1 blueprint will be chosen from the Staple Pool, and 10 will be those guaranteed by the desks, for a total of 11.
On a decoration day, blueprints are granted from Blueprint Desks in addition to all 8 usual Decoration blueprints.
- Example 3 | 10 Blueprint Desks | Decoration Day (shop normally offers 8 blueprints)
8 blueprints will be chosen from Decorations, and 10 will be those guaranteed by the desks, for a total of 18.
¶ Card Modifiers
The following Franchise Cards affect blueprints. Additionally, the Cards Coffee Tables, Conveyors, Floor Protectors, Flower Pots, Metal Table, Simple Cloth Table, and Wash Basin change their respective items to a Bonus Staple (neon-purple border) and moves it to the Staple Pool.
| Name | Description | Notes |
|---|---|---|
| Catalogue | Shop offers an additional blueprint each day | |
| Coupons | All blueprints cost 25% less | |
| Double Homework | Gain two copies of blueprints from desks | Copies do not replace other shop blueprints, but appear in addition to the usual quantity |
| High Tech Suppliers | Shop blueprints have a 25% chance to be upgraded | Also applies to rerolls |
| Loyal Customer | Receive a new blueprint when purchasing | Does not apply to Copies produced by Copying Desk |
| Second Helpings | 50% chance that blueprints can be purchased again | |
| Supplier Error | Shop costs are randomized | Costs range from 0–250 |
¶ Tips
- From the start of a new run, the Research Desk will remain in the Staple Pool until one is purchased. With this in mind, players can store the first Research Desk blueprint produced by the shop in a Blueprint Cabinet, then wait for another copy to appear in the coming days. Since early shops offer Staples far more commonly than other items, players can quickly secure two Research Desks, by purchasing one and using it to upgrade the other to a desk of their choosing (see section on Staple Pool for more on mechanics involved).
- When rerolling, players may wish to maximize their blueprints in order to see as many potential options as possible. This can be done by preparing a Copying Desk and several Blueprint Cabinets on the previous day, which will grant multiple copied blueprints for the sole purpose of rerolling. A slower and more difficult method involves the use of several Blueprint Desks, since if the number of desks exceeds the number of blueprints offered by the shop, it will be forced to produce additional copies (see section on Blueprint Desk for more on mechanics involved).
