U: Hello, I am looking for a moderately priced restaurant that serves traditional food.

S: There are no restaurants matching your request. Would you like a different one?

U: Please find moderately price restaurants that serve spanish type of food.

S: The only restaurant fitting such criteria is La Tasca.

U: Is this restaurant known for their surface?
S: Do you mean service?  If so, there were several complaints about the service there.  Only two people really had anything positive to say.
