U: I'm hoping to find a moderately priced korean restaurant.

S: I'm sorry, we don't have anywhere that matches that description.  Is there somewhere else I can try and find for you?

U: Can you run one more search for korean cuisine in the centre area please?

S: There is only one Korean restaurant in all of Cambridge, but it's expensive, not moderate.

U: Okay what about spanish cuisine then?

S: la tasca is a spanish restaurant located in the centre. Can I book that for you?

U: How big are the food portions?
S: Most people felt that the portions at La Tasca were large, but there is a comment from a past guest who thought the portions were a bit small for the price.
