U: I'm looking for a halal restaurant with moderate prices.

S: Sorry, I could not find any restaurants matching that description.

U: What about a different moderately priced restaurant in the east?

S: I have 3 that fit your request.  Curry prince, rajmahal, and pizza hut fen ditton.  Are you interested in any of these?

U: Yes I would like Curry Prince.

S: May I book that then for you?

U: Do they serve naan that is a decent price?
S: From what I can find, previous customers of the Curry Prince have said that the naan is well made and very affordable.
