Eating Out
- Rules For Eating Out
- Lunch is usually served between 11 am and 1 pm and dinner 5 pm to 10 pm. Do not forget to tip your waiter or waitress (20 % at a "sit-down" restaurant). Service is almost never included in the price of the meal. Sometimes, if you eat with a group of people over a certain number, the restaurant will add a service charge to your bill, which means you do not have to leave a tip.
- Food Specialties
-
American culinary specialities vary considerably by region. Some popular examples include:
Appetisers: crab cakes, oysters Rockefeller, crab soup and Waldorf salad.
Main courses: chili con carne, burgers, chicken or shrimp gumbo, jambalaya and country ham.
Alcohol and cocktails: bourbon, eggnog and mint julep.
Baked goods: corn bread and peanut brittle.
Desserts: president's cake, red velvet cake and King cake.
