There's a Red Rocket gas pump outside with some cars near the pump. The building is relatively small. There are four radroaches inside. There are mostly shelves and a counter with a cash register and a safe behind the counter. The interior is also noticeably larger than the exterior.
- Tales of a Junktown Jerky Vendor next to the right register.
- Tumblers Today can be found south of Willy's grocer, in a wooden shelf on the second floor of a ruined building, near some stimpaks, a scoped .44 Magnum and an ammunition box with .44 Magnum rounds.
- Three bottles of Nuka-Cola can be found in the broken refrigerated shelves in the southeast corner of the store.
Willy's grocer appears only in Fallout 3.
