For a weekend stay at the Inn, ate dinner at the Inn on a Friday and Saturday night. Both were the most expensive meals I have ever had in my life, but well worth it.
Recommend you ask for a table against a wall, ideally on the outside of the building, as there is a lot of movement in the restaurant, and our first meal had my chair bumped into a number of times by the staff. The second meal was at the front windows, and was much more peaceful and better.
The food is magnificent, as are the drinks. The first night my wife and I went with wine, and we're not serious wine specialists, so the staff was understanding and helpful, helping us pick what we wanted, rather than treating us like tourists and making selections for us. That meant a lot. The second night we went with beer selections, which were magnificent.
Service: this is not ultra-heavy and intensive service like some may expect, with the waiters placing your napkin in your lap, and your water glass refilled after every sip. The staff is much more hands-off, yet fully attentive. The approach here is more about the food and drink, than going out of their way to show to you how great they are.
The food was wonderful. Without a doubt, it was the best tenderloin of beef I've ever had in my life. Also went with lobster and some other selections, and they were excellent. Both nights I went with the cheese selection for dessert, and the Cheez Guy, complete with his rolling cow sculpture table, was thoroughly enjoyable, impeccably knowledgeable, and helped us picked cheeses which we would enjoy, and did.
Bottom line: this was a wonderflu splurge for my wife's birthday, and was a fantastic memory for the two of us to share. It's very expensive, but well worth the time it takes to get there, and the money you're spending.
