I'm looking for a cheap indian restaurant please.
Sure, there are a number of cheap Indian restaraunts.  What area of town are you looking for? 
I'd like someplace in the center of town.
There are three places that match that criteria which are the Kohinoor, The Gandhi, and Mahal of Cambridge. Would you like information about one of those restaurants? 
The Gandhi would be perfect. Could you book it for me for tuesday.
Sure, I'd be happy to reserve that for you. How many people are in your party and for what time?
5 at 11:15 on Tuesday. 
Booking was successful. The table will be reserved for 15 minutes.Reference number is : WF5PM422. thank you for inquiring with us
Great. Can you also help me find somewhere to visit in town around that same area?
I found few places you can visit. Do you care if you pay entrance fee ?
It is not really that necessary .
No the fee is not an issue. 
Just choose one and tell me the type, address, and postcode
Old schools is an architecture attraction. The address is trinity lane. The postcode is cb21tt. Anything else today?
That is all I needed today. Thank you for your help.
You're welcome and enjoy your visit.
