# Kettle Street Noodles

> Ramen, rice bowls and small plates for pickup or delivery. A takeout reference store for shopping agents.
> Reference test stores. Nothing here is for sale: test cards only, no goods ship.

Reference store operated by UCP Sandbox. UCP version 2026-08-25. Preview: the UCP spec for this kind of store is still settling, so this store will change.
Everything an agent can do here is also possible for a person on the same pages: same products, same carts, same orders.

## Machine surfaces

- UCP profile: https://food.ucpsandbox.com/.well-known/ucp
- UCP REST binding: https://food.ucpsandbox.com/ucp/ (OpenAPI at https://food.ucpsandbox.com/ucp/openapi.json)
- MCP endpoint (JSON-RPC): https://food.ucpsandbox.com/mcp
- WebMCP: storefront pages register tools on document.modelContext

## Catalogue

- [Ramen](https://food.ucpsandbox.com/collections/ramen): Six builds of every bowl: choose noodles and spice. (7 products)
- [Rice bowls](https://food.ucpsandbox.com/collections/rice-bowls): Choose the rice and the size. (6 products)
- [Small plates](https://food.ucpsandbox.com/collections/small-plates): Gyoza, tempura, karaage. (8 products)
- [Sides](https://food.ucpsandbox.com/collections/sides): Rice, pickles, kimchi, soup. (5 products)
- [Drinks](https://food.ucpsandbox.com/collections/drinks): Sodas, tea, and a lager for the over-21s. (7 products)
- [Desserts](https://food.ucpsandbox.com/collections/desserts): Mochi, dorayaki, kakigori. (4 products)
- [Add-ons](https://food.ucpsandbox.com/collections/add-ons): Egg, chashu, corn, extra noodles: add them to any bowl. (8 products)

## Policies

- Pickup: Pickup orders are ready in about 20 minutes at Kettle Street, 418 Division St. Say your pickup code at the counter or find your bag on the shelf by the door. Nothing is cooked in this test store: every order is simulated and its status moves on a timer.
- Delivery: Delivery runs within three miles of Division St in 30 to 45 minutes for $3.99. Nothing is delivered from this test store: every order is simulated.
- Cancellation: Orders can be cancelled free of charge until the kitchen starts cooking, about a minute after they are placed.
- Refunds: Food cannot be returned. If an order is wrong or something is missing, tell us within an hour of pickup or delivery and we refund the item or remake it.
- Allergens: Every dish lists the allergens it contains: gluten, egg, soy, peanut, shellfish, dairy and sesame. The kitchen is small and shares fryers and boards, so no dish is guaranteed free of anything. Use the Avoid filter to hide dishes that contain what you avoid.
- Alcohol: Alcohol is sold only to adults 21 and over. Bring photo ID to pickup; for delivery the driver checks ID at the door and takes the drink back if nobody of age is home.

## Testing

- Payment instruments: instr_1 (Visa …1234, succeeds); instr_2 (Mastercard …5678, succeeds); instr_fail (Visa …0000, declines)
- Discount codes: 10OFF, WELCOME20, FIXED500
- Fulfillment: pickup (pickup-asap, pickup-45, pickup-60); shipping (delivery-asap, delivery-60)
- Allergen tags on products: gluten, egg, soy, peanut, shellfish, dairy, sesame. Age-restricted items carry the tag 21+.
- Fees: Kitchen tip (0/10/15/20%), chosen at checkout and shown as a fee total line

## FAQ

- Q: How long does pickup take? A: About 20 minutes. The order page shows Received, Cooking, Ready for pickup and Picked up, and moves on a timer because nothing is really cooked.
- Q: Do you deliver? A: Within three miles of Division St, in 30 to 45 minutes, for $3.99. It is a test store, so nothing actually arrives.
- Q: Can I order alcohol? A: Yes if you are 21 or over. You confirm your age at checkout and bring photo ID to pickup.
- Q: Is the food real? A: The menu is real enough to test against; the shop is not. This is a reference store for testing agents. Test cards only, nothing is cooked.
- Q: Which payment methods do you accept? A: Test instruments only: Visa ending 1234 and Mastercard ending 5678 succeed; Visa ending 0000 is declined.

Questions

Can UCP agents buy from food.ucpsandbox.com?
Through its REST and MCP services, an agent can search the catalogue, build a cart and start a checkout. The service answered our check. This is what the store declares and what our check reached; an observed agent run shows how far an agent actually gets.
Is food.ucpsandbox.com ready for UCP agents?
food.ucpsandbox.com publishes a valid UCP profile and scores 96/100 (grade A). 2 things to fix: fix broken spec or schema URLs and publish Organization schema (JSON-LD) on the homepage.
What is a UCP profile?
The JSON file a store publishes at /.well-known/ucp to tell UCP agents which services it offers, how to call them and how it takes payment. The spec calls it the business profile. food.ucpsandbox.com's is 5.7 KB, written for UCP 2026-08-25. What goes in a UCP profile.
How was food.ucpsandbox.com checked?
With public requests on 17 Oct 2026: we read /.well-known/ucp and robots.txt, validated the profile against UCP 2026-08-25, checked that its spec and schema links resolve, and called its REST and MCP service. No sign-in and no purchase. How we check.
