user: Hello, please find me a place to dine in the north area that serves polish food.

assistant: There are no restaurants that meet that criteria. Would you like me to look for Polish food in another area?

user: Yes please. I would just need it to be in the cheap price range.

assistant: I do not have any polish restaurants in the cheap price range. Would you like a different restaurant or cuisine?

user: Yes, let's try italian food.

assistant: Great. Da vinci pizzeria is a cheap italian restaurant in the north. Would you like me to make a reservation there?

user: Book a table for 1 person at 16:00 on Saturday.
