U: Great, I sure hope so. I need a restaurant.

S: I can help you with that. There are over 100 restaurants in Cambridge. Are you in the mood for a particular food? Or would you like a certain area?

U: Yes, I would like an expensive restaurant that serves Indian food.

S: Sure, there are 14 expensive Indian restaurants. Do you have an area in mind?

U: I don't care about the about the area. I need a table for four.

S: What day and time would you like your reservation?

U: I'd like Sunday at 18:15, please.

S: I'm sorry, there are no available table on Sunday for 4 at 18:15. Would you like to book another day or time slot?

U: Let's try 17:15.

U: Does the Tandoori Palace have an extensive nonalcoholic drink menu?
S: They do have a large variety of non-alcoholic drinks on their menu. Is there anything else you'd like to know?
