I'm looking for an expensive restaurant in the Centre.
There are 33 expensive restaurants in the centre of town. Do you have a food preference?
I would really love to find an expensive Polish restaurant.
I'm sorry but there are no expensive Polish restaurants in the centre. Would you like a different type of cuisine or price range?
How about Chinese food?
We have Ugly Duckling, Tang Chinese, HK Fusion, and Sesame Restaurant and Bar. Would you like to book one of those?
Can I have the phone number for the Ugly Duckling restaurant?
There is no phone number for Ugly Duckling.
Okay let's try the Tang Chinese. Is there a phone number for them?
The phone number for Tang Chinese is 01223357187.
I'm also looking for somewhere to go. I'd like to do something entertaining near the restaurant. Are there any museums in the area?
There are a few options. How about primavera, castle galleries, cambridge contemporary art or broughton house gallery. Would you like additional information on either of these?
I'd be interested in the contemporary art.  Do you know how much it costs to get in?
Cambridge contemporary art has free entrance. It is located at 6 trinity street. Do you need any more information?
That's not needed. I am  looking for a taxi to go between the two places, though.
What time would you like to go between the two locations?
Oh, wait. I'm so sorry. Before we book a taxi, can you provide me with the phone number to the art museum?
The phone number is 01223324222
I want to leave the museum by 4:15.
Wonderful. I was able to schedule that taxi for you. You will be riding in a grey Ford. If you have any questions for them, you can reach them at 07508824111.
Thanks so much for all your help.
You're welcome. Can I help you with anything else today?
No, that's everything. I'm sure my trip will be fantastic. Thank you for all the help. Have a good day! 
Okay thank you for calling.
