I ate there once about 10 years ago, and also had a look at the hotel room area upstairs while I was there. Dinner was very good, but I honestly think the high price is a bit of a gimmick. Service was a nice combination of professional but casual; it didn't feel at all stuffy or intimidating. We ate dinner in the dining room but chose to have dessert outdoors on the patio, which was nice. BTW, I wanted to take my parents there for their 50th anniversary, but they declined. My dad said he wouldn't be able to enjoy it knowing how expensive it was.
I once ate at a Michelin 3-star restaurant in Paris. (That year, there were 21 3-star restaurants in all of France.) It wasn't at all casual. Men had to wear jackets, unlike the Inn at LW. The experience was a bit intimidating. There were more staff serving than there were diners, even though every table was occupied. The original art nouveau interior was stunning. I don't remember what I had anymore (but I can recall other, much less expensive meals in France and elsewhere) except for the amuse-bouche we were served, chopped razor clams in a cream sauce served in their beautiful shells. It was one of the most delicious things I've ever eaten.
