the Gourmet Burger Kitchen has exactly what you are looking for. It is located at Regent Street City Centre. It is in the center of town. Phone number is 01223312598.
I want to find an expensive restaurant that has North American food. Great! Can you tell me the area of town that's located in, and give me their phone number, please? Excellent. I also need a train booking. It should leave after 18:45 and depart from kings lynn.
