I am looking for a restaurant in West Cambridge, in the cheaper price range please.
There is la margherita, an italian restaurant and thanh binh, a vietnamese restaurant. 
Yes, I am interested in the one that serves Italian food.
How many people will be dining, and for what date and time?
There will be 4 people and I would like to reserve it for Wednesday at 6:15.
I wasn't able to make that reservation. Would you like to try a different time?
How about 17:15?
That booking was successful. Your reference number is XF1JEIBG.
Great.  Can you also tell me about Churchill College?  I am thinking of visiting that.
Churchill college is on the west side on Storey's way. There is no entrance fee. The phone number is 01223336233. Anything else I can tell you?
I think that was it. Thank you for your help!
You're welcome. Have a great day!
