I need a place to stay that is cheap. 
Okay and what area will you be staying in?
I need a place in the center of town, and I would prefer a hotel over a guesthouse.
I have three hotels in the centre, one is moderately priced and then there are two expensive ones.  Would you like to book one of them?
I want to book one of the expensive ones. 
The expensive ones are the Gonville Hotel and University Arms Hotel. Both offer free wifi and parking. The Gonville is 3 star rated, and the University Arms is 4 star.
Great. Can I book the University Arms for 2 nights for 4 people starting Sunday please? I'll need a reference number.
OK, you're all set. Reference #MEGFYQHA. Is there anything else I can help you with today?
Can you help me find a Hungarian restaurant, also in the centre of town?
I'm sorry, there are no Hungarian restaurants in the centre of town, would you like another location?
Is there and Indian restaurant available in that area?
There are 9 indian restaurants. Do you prefer cheap or expensive?
I would like expensive please.l
There are several options in that area. How about Curry Garden? I hear it's great.
Can you book a reservation for me?
Absolutely, what day would you like reservations?
I would like to book it fro Sunday at 14:45.
How many people will be dining?
4 people will be dining. 
Your table is booked, ref#9BZUL5GV. Is there anything else I can help you with today?
