Can you help me find a 4 star hotel in Cambridge?
There are three 4-star hotels. What area would you prefer?
I would prefer to stay in the west part of town.
There are two choices, one is in the expensive price range, the other in the cheap price range. Which one is preferable to you?
I don't have a preference. 
How does the huntingdon marriott hotel sound to you? May I book you there?
Is this the expensive or cheap price range option? How much does it cost per night?
They are in the expensive price range.
Ok. I'd like the address, please.
The huntingdon marriott hotel is located at kingfisher way, hinchinbrook business park, huntingdon.  Would you like to book a room?
Not at this time, but I would like to find a place to eat. Ideally an expensive German restaurant in the same area.
Unfortunately, no such restaurant exists. Would you like to look in a different area, price range, or cuisine type?
How about one that serves British food
There are two places Graffiti and Travellers Rest which would you like to try?
Graffiti sounds good. May I have their phone number, address, and postcode, please?
The address, phone number and post code for Graffiti are Hotel Felix Whitehouse Lane Huntingdon Road, 01223277977, cb30lx. 
I'll need a taxi from the restaurant back to my hotel. I'd like to leave the restaurant by 11:30.
Ok, I've booked you a taxi from Graffiti to Huntingdon Marriott Hotel at 11:30. Anything else I can do for you?
Can I get the phone number of the taxi service and what car type will I be looking for?
number is 07435240506, and it is a black audi. 
Great, you have been very helpful, that's all I need for now.
You are very welcome. Thank you for contacting Cambridge Towninfo Centre. Have a great day.
