U: I am looking for a cheap restaurant that serves Cuban food.

S: I am sorry there are no Cuban restaurants in the cheap price range. Is there anywhere else you will like to search for?

U: Could you look for Chinese restaurants instead?

S: There are 3 in the centre and one in the south. Charlie Chan is one of the cheap Chinese restaurants in the centre.

U: Can I get the address and phone number of Charlie Chan, please?

S: Charlie Chan's phone number is 01223 361763 and the address is Regent Street City Centre. May I help you with anything else?

U: Does this restaurant serve alcohol?
S: Yes, Charlie Chan serves alcoholic beverages. They have an extensive cocktail menu to pick from. Want a reservation?
