U: I am looking for a cheap place to dine in the centre of Cambridge.

S: If you are interested in Chinese food, there is Rice House located at 88 Mill Road City Centre in the cheap price range.

U: I prefer Russian food actually.

S: I can't find any cheap Russian restaurants.  Are you open to moderate price?

U: No. It really does need to be cheap. What about chinese in the centre?

S: There are 3 restaurants matching that, Charlie Chan, Rice House, and Golden House.

U: Are the locations there nice?
S: Charlie Chan is located in the heart of the downtown business district which is both a positive and a negative to some. The Rice house has mixed reviews with some not liking the location and others finding it very nice. The Golden House is said to be in a fantastic location. Would you like more information on any of these restaurants?
