I am looking for a place to dine that serves north american food located within the town centre. The only North American restaurant in the centre is Gourmet Burger Kitchen. It is expensive. Would you like to book a table? Can you tell me the postcode and phone number for Gourmet Burger Kitchen? Sure, the postcode is cb21ab and the phone number is 01223312598. How else may I assist you? Yes I would also like to visit some colleges in the same part of town. Is that possible? There are 13 colleges in the Centre. 3 have nominal entrance fees of 2.50 pounds or less, the rest are free to visit. Do you have any preference? Could you give me the address for one of the free colleges? Christ's College is free and is located at Saint Andrew's Street with a postcode of cb23bu. Could I be of further assistance? Yes. I'd like a taxi to pick me up at Christ's College and take me to the restaurant. I'd like to leave the attraction by 19:00. Ok, your booking has been completed.
