The dining room is a room built in Fallout Shelter.


The diner allows dwellers to create food in a vault. Its food production is correlated to its occupants' Agility trait. It is one of the facilities available at the start of the game, and a facility created in the tutorial. Fully merged and upgraded diners can have themes applied to them.

Food production

To increase the speed at which food is produced, place dwellers with better Agility in this room.

Higher vault dweller count increases the demand for food. If food supply runs low, dwellers will start to lose health.


The diner, like other rooms, gains a production bonus from being connected to another of the same type and level. The room will gain a +2 production bonus for each connected room. Upgrade costs will be 25% cheaper for a double room and about 34% cheaper when upgrading a triple room vs upgrading 3 single rooms.
