user: I am looking for places to go in the centre of town.

assistant: There are many places to go in the centre of Cambridge: marvelous architecture, colleges, museums, theatres, and more. Are any of these options particularly interesting to you?

user: I'm not picky, I'm totally open to suggestions. Can you pick your favorite and let me know the address?

assistant: Oh, wonderful. I'd recommend Club Salsa, on 1 Station Road. It's a nightclub and the entrance fee is 5 GBP, but it's worth it!

user: I'm also looking for a hotel. I want a place with a 3 star rating and free wifi.

assistant: I have 5 results of places with 3 star ratings. To help narrow it down a bit, what area do you prefer and what price range?

user: Sure, how about something cheap?

assistant: There are no cheap hotels with that search. Would you like a different price range?

user: Anything moderately priced in the 3 star rating, with free wifi, please.

assistant: bridge guest house is a moderately priced 3 star hotel in the south with internet. Do you want to make a booking?

user: Yes, please book me for 7 people and three nights starting on Tuesday and please also give me a reference number for the booking. I also would like a taxi.

assistant: Success! I was able to book that for you and your reference number is 8E1NHOEK . Anything else?

user: Yes I need a taxi to leave the Club Salsa by 17:30 heading back to the hotel.

assistant: A black Toyota will pick you up at 17:30 at Club Salsa to take you back to the Bridge Guest House. Contact number is 07280181013. Will that be all?

user: That's great! That's all I need. Thanks.

assistant: Great! Thank you for allowing me to assist you. Goodbye!
