U: I want a jamaican food restaurant in the centre part of town.

S: There are no jamaican restaurants in the center part of town. Do you have another cuisine or area preference?

U: Are there any International restaurants in the centre?

S: There are two international restaurants in the centre area, both moderately priced.  Would you like their addresses?

U: I don't care.

S: May I recommend Bloomsbury Restaurant which is an International restaurant in the centre and is moderately priced?

U: Is there a nice outdoor seating area?
S: Yes, there is a good outdoor seating area at Bloomsbury restaurant. One person said that it was large enough for groups and it made them feel comfortable. Is there anything else I can help you with?
