U: I am looking for a restaurant please.

S: Okay! What kind of restaurant would you like to dine at?

U: One that serves modern American food.

S: I'm sorry there are no matches. Would you like me to try a different food type?

U: I guess I can do Spanish food, try to find something in the Centre area, please.

S: There are two options for Spanish food in the centre. One is moderately priced while the other is considered cheap. Which would you prefer?

U: I'd like the moderately priced one please.

S: It's called la tasca. I'll need more information if you'd like to book a table.

U: Is the service at La Tasca high quality?
S: The service at La Tasca does not seem to be high quality. There are a few people who were happy with their service, but most seemed to feel as though the staff was not very good.
