U: I am looking for an Afghan restaurant in the expensive price range.

S: There are none in that range, perhaps something else?

U: Okay, how about mexican food?

S: Chiquito Restaurant Bar fits that criteria. Would you like to make a reservation?

U: Yes, please. 7 people at 18:30 on tuesday.

S: Unfortunately we can not book you for that date and time. Would you like to try another date or time perhaps?

U: How about 17:30 instead?

S: That's a better time, your reference number is IV21ENWM and the table will be held for you for 15 minutes. Is there anything else you need?

U: Yes, I need a place to stay with free wifi. The hotel should have a 0 star rating. Do you have anything like that?

S: Sure, there is one option. CityRoomz, shall I book a room for you?

U: Can you first tell me if the rooms there are quiet, or is the hotel in a quiet area?
S: Cityroomz gets some high marks for the noise level with customers saying there is very little noise and in a quiet area. Would you like to know more about them?
