I would like to find an expensive hotel to stay in during my visit. 
I can help with that. What area will you be staying in?
The area does not matter. But will for sure want it to be an actual hotel. 
I have the in the Huntington Marriott hotel city center that is rated 4 stars and include free parking and free wifi. Would you like me to check availabiltiy?
Yes, please book it if possible.
What day would you like to leave
I don't want to leave. I want to stay for 3 nights starting on Tuesday. There will be 6 of us.
And you never have to leave if you don't want to. I have booked a reservation at Huntingdon Marriott Hotel and the reference number is EQNKY1ZC. Anything else?
Yes, are there any moderately priced northern european restaurant, if no northern european, modern european will do.
There are 3 restaurants matching your query. Do you prefer the south or the centre?
I would like the restaurant in the same area, Cambridge, please.
And would you prefer the south of Cambridge or the centre of Cambridge?
I'm not picky with the area. I just want it to be moderately priced.
I'm sorry, there are no moderately priced hotels in this area. Would you like to try another?
I was looking for a restaurant.  I already have a hotel reservation
There are a couple in the centre area and one in the south area. Do you have a preference?
I would like one that serves northern european food, if possible.
We have quite a few choices for you today, how about de luca cucina and bar, you can a few drinks while your there!
Thats sounds great. can i get the area and address ?
The area is the centre. The address is 83 Regent Street. Is there anything else I can help you with?
I'll need a taxi that leaves the restaurant by 22:00.
Will you be going back to the hotel or somewhere else?
The hotel I guess.
