Originally known as the Canteen, the Eatery was the common name for the combination of dining hall and grocery available to habitat residents for everyday dietary needs. Eateries were located on each Culinary Floor at the outer wall and inner circle, with entrances at the compass points. Like other habitat-run buildings, they were distinctive by their very plainness, showing a dark gray checked pattern over a white stone-like facade.

Eateries were open 24 hours a day, seven days a week, with most of the staffing happening via Community Tasks and supervised by experienced workers.

In the decades following the Catastrophe, a co-op that allowed residents to order a meal and have it picked up and stored at a small shop on the residence floors for residents to bring home established itself. To-Go Shops became a staple on the residential floors.
