Restaurant

Restaurants exist in The Sims: Hot Date, several Sims 2 expansions, and in The Sims 3.

The Sims 2
Nightlife, Open For Business and Bon Voyage each contain restaurant objects and lots.

A Sims 2 restaurant needs these objects:
 * A host desk for the host
 * A chef stove
 * At least one chair at a bar or a kitchen table.

In Open For Business players could have their Sims operate their own restaurants, with hosts, waiters and chefs.

The Sims 3
The Sims 3 contains restaurant rabbit holes.
 * Diner
 * Bistro
