U: I need to find a vietnamese restaurant in the moderate price range.

S: I'm sorry, we don't have anywhere that matches those criteria.  Is there something else I can find for you?

U: Can you try chinese?

S: I have four choices for Chinese restaurants. Three are in the center of town and one is in the north. Any preference?

U: I'm a pathological liar. I don't want Chinese. I actually want British food.

S: All righty, then. We have five moderately priced British restaurants. I'm almost afraid to ask, but does location matter?

U: I'd like it to be in the centre please.

S: There are 4 options for british food in the centre. restaurant one seven, the oak bistro, the copper kettle and cotto. Do any of those sound good to you?

U: recommend one and book a table for 3 people at 17:45 on tuesday and get me the reference number

S: The oak bistro. Booking was successful. The table will be reserved for 15 minutes.
Reference number is : TMOV7WRE.

U: Do you know if it has various non-alcoholic drink options?
S: Yes, The Oak Bistro does have various non-alcoholic drink options for those looking for that type of beverage.
