U: Hi, I'm looking for an expensive restaurant that serves Moroccan food in Cambridge please.

S: I'm sorry, there are no expensive Moroccan restaurants in Cambridge.

U: Ok, how about Chinese food then?

S: There are several. If you don't have a preference as to where in town you eat, might I suggest the good luck chinese food takeaway?

U: I would like to have good restaurant service, so does this restaurant have friendly and responsive staffs?
S: Customers who have previously dined here have said that the service was excellent and extremely fast, but others have said that the service was poor and staff clueless.
