U: Find me a moderately cheap restaurant in Cambridge that serves russian food

S: There are no listings with those criteria. Do you want to change some criteria?

U: How about British food instead?

S: There are 5 restaurants which match your requirements. Are you looking for a restaurant in a particular part of town?

U: No any part of town will work.

S: Would you like me to book you at The Oak Bistro at 6 Lensfield Road?

U: Can I just get the area, phone number, and postcode of it?

S: The Oak Bistro is in the area of centre, the phone number is 0122332361, and the postcode is cb21ab.

U: Thanks. Also I am looking for a guesthouse hotel with 2 stars in the north.

S: I'm very sorry but there are no results matching your criteria. Would you like to change the star rating, or try a different area?

U: Can you see if there is just a normal hotel in the north? It still needs to be a 2 star.

S: Yes, I have 2 hotels in that area and with that rating. The Ashley hotel or Lovell Lodge. Would you like me to book one of them?

U: Yes, please. I need a room for 1 person, 3 nights. I'll be arriving on Saturday. The Ashley is fine.

S: I have book it for you. Your reference nummber is:  KKCAOAA4

U: I appreciate it, do the rooms in this hotel have comfortable beds?
S: The customers at the Ashley Hotel say that the beds are comfortable, comparable to beds at one's home.
