We visit this restaurant for lunch once a month. It's a fairly high class establishment, with a more casual feel on the first floor, and a more formal feel on the second floor. The oysters are first class. East and west are a good choice, although I wasn't a fan of the "New Zealand" ones. ( too big)
The ravioli consome is really good. You don't always need a reservation but one is recommended as we have missed it a few times, especially at lunch.
