The service when we were there was pretty prompt, but I would definitely check in WAY early. We waited over 40 minutes after our ADR time to be seated. It was chilly outside and that stuffy, tiny lobby was very OLD by the time we got to our table. I think that must have clouded me about the experience, because I came away feeling less than enthused. The food was good, our server was nice and prompt, but I don't have any real desire to go back.
Hope you don't have too long of a wait!!
