Can you find me an expensive indian restaurant?
Curry garden is in the expensive price range and serves Indian food.
Great, can you book me a table for the same group of people at 19:15 on the same day?
Success! Your reference number is DBUN9LUJ. They'll hold your table for 15 minutes, in case you're running a little late. Need any other help?
