U: I am trying to plan my trip in Cambridge and need a place to dine.   I need something kind of moderate for price and on the west side.

S: We have three restaurants.  Do you prefer British, Indian or Italian cuisine?

U: How about thai?  Are there any thai restaurants in the west of the moderate price range?

S: I'm sorry, there aren't any moderately priced Thai restaurants in the West.

U: That is okay. An Indian restaurant would be great, which place do you recommend?

S: we still cant find any of that criteria. can we change location?

U: Yes try a different location.

S: I can't find any indian places in the moderately priced range. Can I try something else?

U: maybe you could check any price range.

S: kohinoor is a cheap indian restaurant located in the centre.

U: Do they serve decent Biryani at a reasonable price?
S: No, guest reviews indicate that the food, including biryani, is too pricey. Would you like me to find another option for you?
