U: Yes I would like to find a restaurant that is in the cheap price range on the west side of town.

S: Would you prefer italian or vietnamese food?

U: Italian. Would you reserve a table for 5 for me? I'd like that to be at 14:00 on Tuesday.

S: Booking was unsuccessful for la margherita. Would you like me to try booking for the Vietnamese restaurant called thanh binh?

U: Can you check if they serve alcohol there?
S: Yes, I can check to see if they serve alcohol. Thanh Binh does serve alcohol. Is there a specific drink you're interested in learning more about?
