Task-oriented dialogue about: restaurant

I am looking to dine out in the centre part of town and I would like to find a place that serves north american food.
I have one, Gourmet Burger Kitchen.
I want to book a table for 5 people at 13:00 on saturday.
Unfortunately, they are all full at that time. Would you like me to try another restaurant?
Yes. Please look for a different place in the same area and price range.
I'm sorry but Gourmet Burger Kitchen was the only North American restaurant in the centre area. Would you like for me to try another area?
Not right now. Thank you for your time.
Okay, please let me know if you need anything else.
