U: Good morning, I need help finding a restaurant that serves bistro in the moderate price range.

S: I couldn't find a restaurant with the attributes you are looking for. Would you like something else?

U: How about one with british food?

S: There are 5 restaurants serving british food. Do you have a preferred area?

U: Is there any options that have halal foods available?

S: I'm afraid there are no halal options at this restaurant. Do you have a preference in location?

U: I do not have a preferred area.  Which ones have a table available for 6 people at 12:30 on Tuesday?

S: Is there a price range you would prefer to stay within?

U: No I do not need to stay within a price.

S: I have Restaurant One Seven in the moderate price range. Would you like me to book a reservation?

U: Yes, please.

S: The booking was unsuccessful, do you have any other preference?

U: I just need a restaurant in the same area and has the same price range.

S: Sure. I booked you a table in the oak bistro which is in the center part of the town. Your reservation number is CMJ6WM0Z.

U: Does this place have highchairs for babies?

S: The Oak Bistro does have high chairs. Does that answer all your questions?

U: Is al fresco dining (in the outdoors) available at The Oak Bistro?
S: Yes they have very nice and pleasant outdoors seating. You will love to have your party out there and take in sights.
