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: Is it in the expensive range?

S: Yes it is. Would you like me to send you their address?

U: Can you book me a table for one on Friday at 13:45? I will need the reference number as well.

S: Booking was successful. The table will be reserved for 15 minutes. Reference number is : MM5BYTYE. Do you need anything else?

U: Yes, please. I'm looking for a hotel on the east side.

S: There are several, do you have any other preferences like price range or rating?

U: I would like it to be in the Expensive range.

S: There is one expensive hotel on the east side. It is the express by holiday inn cambridge. Would you like me to book that for you?

U: Is it well cleaned?
S: Two reviews for Express by Holiday Inn Cambridge note that the rooms are clean and show signs of being recently and frequently maintained. Two other reviews state the opposite.
