U: Hi.  I'm trying to find a restaurant that serves Welsh food.  Can you help me?

S: no information found

U: How about Portuguese food? I don't care about the price range.

S: which area of town would you prefer?

U: Portuguese food in any area

S: There are two restaurants serving portuguese food. Nandos in the South and Nandos in City Center. Would you like further information on either of those?

U: Could you give me the phone number and address of the Nandos in City Center?

S: Nandos can be found at 33-34 Saint Andrews Street and can be reached at 01223 327908. Can I assist you with anything else?

U: Do they have nice indoor features to look at?
S: It seems from reading past guest reviews that the interior is quite dated and needs to be refreshed. Is there anything else that I can help you with today?
