I am looking for a restaurant in the city center that serves modern European food.
I can recommend the Michaelhouse Cafe. Would you like me to make a reservation?
Yes, I would like to reserve a table for 5 people at 18:00 on Wednesday.
I'm sorry, but there aren't any reservations available at michaelhouse at that time.   Would you like to try a different restaurant?
Yes, please find me another restaurant in the city center in the same price range.
michaelhouse cafe is a nice place and the only option available.
