U: Please find me a place to dine that serves vegetarian food that's in the expensive price range.

S: Oh dear. I did a search for a cheap vegetarian restaurant and my computer doesn't list one. Would you like me to check the moderate range?

U: I am actually wanting the restaurant to be expensive and in the centre of town.

S: I am sorry but there are no restaurants matching that criteria. Would you like to try another price range or part of town?

U: Are there any expensive french restaurants in the centre?

S: Yes, one of my favorites.  Cote on Bridge Street City Centre.

U: Can you book a table for 5 at 17:00 on friday.

S: I booked a table for your party of 5 at Cote for Friday at 17:00. Your reference is B3LAV5Z1 and the table will be reserved for 15 minutes

U: Do they have outdoor seating?
S: Yes, Cote offers a nice area for outdoor dining. Do you have any other questions about the restaurant?
