There is one restaurant that fits what you are looking for. Would you like to book a table at the Gourmet Burger Kitchen?
I'm looking for a expensive restaurant that serves north american food. Absolutely, I would love to book a table for two at 17:30 on Thursday, please.

{"__type": "NotifyFailure", "service": "entity", "entity": {"__type": "Entity", "book time": "that time"}} {"__type": "Request", "service": "entity", "values": ["book day", "book time"]}
Unfortunately there are no tables available at that time. Are you interested in a different day or time slot?
