U: I'd like to find a cheap Indonesian restaurant. Can you help?

S: Unfortunately, we do not have any Indonesian restaurants.  Would you like Thai food?

U: What kind of restaurants are in the west that's cheap?

S: There is an Italian restaurant, La Margherita and a Vietnamese restaurant called Thanh Binh.  Would one of those work?

U: Yes, could you give me more info on the Vietnamese restaurant?

S: Their address is 17 Magdalene Street City Centre.

U: could you give me their postcode?

S: Their postcode is  cb30af.  Would you like to book  a table?

U: Does Thanh Binh serve high-quality vermicelli noodles at a good value?
S: While the reviews don't mention specific items, all say the food is great and affordable. Will that work for you?
