I am looking for an expensive Indian restaurant in Cambridge.
There are 14 expensive restaurants that serve indian food.  What part of town would you like?
I want the location to be in the west.
Cocum is a nice Indian restaurant in the West in the expensive price range. Would you like to book a table? 
Yes, I need a table.
Okay, I can help with that. What day and time would you like to dine and how many people should I have the reservation for?
On Thursday at 5:00. I also need a hotel in the same area. No need to have free parking.
I am unable to find a hotel that meets your criteria. Would you like help with anything else?
are you sure?  it should be the type of a hotel
Yes this is correct there are none available sorry. Do you have any other preferences ? 
How about one that has free parking?
