Servers stand at a table's corner instead of on top of guests, and carry the plate they're delivering. Each dish has its own plate art.
An empty seat shows a dirty plate after the guest leaves, money once they've paid, and a clean place setting when it's ready again.
A graphics pass toward the RimWorld and Prison Architect look: wood floor in the dining room, checker tile in the kitchen, sidewalk and road outside, a shop front with a glass door, a brick kitchen wall with a swinging double door, wood tables, and chairs turned to face their table.
Guests face the way they're sitting, and arriving guests form a single-file line on the sidewalk.
Cooks start in the kitchen, idle servers wait by the door or the kitchen, and the pass sits at the kitchen door.
Fixed three ways people could get permanently stuck in doorways and lines.
CHEF!
