There are 14 choices. I would recommend Tandoori Palace in the west. The phone number is 01223506055. Would you like me to book it for you?
Sure!  I need a table for just me on Tuesday at 16:45, please.
Okay. Your booking was successful! The reference number is GRJ6E9C3. Your table will be reserved for 15 minutes. 
I'm also looking for places to go in the city centre.
We have 44 options for you. Would you like to narrow it down by attraction type?
It should be in the same area as the restaurant.
I have 5 places for you, 4  have free entrance fee and one has 2 pounds entrance fees.Which one will you prefer
Lets pay, this trip is a business write off, so money is no object, Ill take the 2 pound entrance fee.
