U: Hi there, I'd like to find a good place to eat in the city centre tonight, but I'm looking for somewhere cheap. Have you any good recommendations?

S: Absolutely! I have about 15 restaurants that are in that area and price range. Can you tell me what type of food you might be trying?

U: You know, I'd really like to try north african food.

S: I am sorry, but there are no cheap restaurants in the centre serving north african food. Would you like to keep searching for another type?

U: How about some chinese food?

S: There are three restaurants, Charlie Chan, Rice House, and Golden House. Would you like to book a table at one of them?

U: How about Rice House? I'd like to book a table for two at 19:00 on Monday.

S: Fantastic! Your table is booked for Rice House at 19:00 on Monday, and the reference number is T0NP4V1O. Is there anything else you need help with?

U: Yes can you tell me if the Rice House has outdoor seating available?
S: Yes, the Rice House offers outdoor seating and customers seemed to really like it. Do you want to know anything else?
