Finding good restaurants usually isn't a problem for language students; ordering at one can be if you don't know appropriate language expressions. What kinds of questions and expressions would you expect to hear between a customer and a server?
HELPFUL TIP: Don't be afraid to ask questions about the menu. In fact, skip the burger and fries, and trying something new will be both a cultural and language experience.
Search the Internet for a restaurant near you, download their menu, and practice taking the roles of a customer and server. Then, discuss the positive and negative points about the restaurant including prices, location, and business hours.
