user: Hello. I'm going out for an expensive dinner and need to find a restaurant. I'd like somewhere in the north, and I'm willing to pay quite a bit of money.

assistant: I'd be happy to help you with that. I have 5 expensive restaurants in the north. Did you have a type of cuisine in mind?

user: Yes, Romanian please.

assistant: There are no options for romanian, can I try something else for you?

user: I guess try European.

assistant: The city stop restaurant is a european restaurant in the expensive price range.

user: Is it in the north? If so, can you reserve us a table for 3 on Friday at 17:45 please?

assistant: I am sorry but the restaurant will be unable to reserve a table for that time. Would you like to try another day or time?

user: How about at 16:45?

assistant: Booking was successful. The table will be reserved for 15 minutes. The reference number is: 0PK0TW8F

user: I'm also looking for a place to stay that offers both internet and free parking.

assistant: There are 29 places in Cambridge which offer both, any other preferences?

user: Hmm, yes. Someplace expensive.

assistant: I can recommend the University Arms hotel in the centre of the city.

user: Great, can you make a reservation for three people for the three nights starting Friday please?

assistant: I'm sorry, I couldn't book that for you, would you like to try another day?

user: No, I need it to be Friday. Can we try it for a one night stay instead?

assistant: Alright! I was able to book your room for 1 night at the University Arms Hotel for 3 people. Your reference number is F13028XH . Can I help with anything else?

user: I'm going to need a taxi as well from the hotel to the restaurant that arrives at 16:45. Could I get the contact number and car type for that?

assistant: Sure! The contact number is 07648846859 and the car is a black audi. Is there anything else you need help with?

user: No, you have been most helpful. Have a nice day.
