Hi, i am looking for a middle eastern restaurant in the expensive price range. 
I am sorry, there are no expensive middle eastern restaurants. Can I look in a different price range?
Yes, can we try a moderate price range.
Sorry there are no moderate middle eastern restaurants either. Do you want to try a different price range?
Hmm, how about Italian?  Expensive.
There are some great ones.  Do you have a preference for which part of town it is in?
Nope! Could you pick your favorite and book a table for me? 2 people at 12:30 on Tuesday, please.
Booking was successful. The table will be reserved for 15 minutes.

I am glad to be of service! Have a wonderful time in Cambridge!
