U: I'm looking for a latin american restaurant in the moderate price range.

S: we don't have that in our records. can you change the type of food?

U: Can you help me find a moderately priced resaturant in the south that serves latin american food?

S: There are no restaurants available matching what you mentioned.

U: How about Italian food. You do have Italian restaurants don't you. Moderately priced and in the south area would work fine for me.

S: The only moderately priced Italian restaurant in the south part of town is the Pizza Hut Cherry Hinton. Would you like a reservation?

U: As long as they serve delicious Arancini, then I would.
S: The main complaint about the food including the Arancini is the small portions. Would you like to know more about the place?
