Yes please. I need a restaurant in the north, same price range as the hotel, and serves swiss food. 
We don't have any such restaurants in the north. Do you want to search for something different?
Can we try for one that serves Indian food instead?
The Nirala is a moderately priced indian restaurant in the north. Can I book you any tables?
