We (four of us) had a celebratory dinner at Lark recently. Overall the food was excellent, but the service was lacking. Either they were short handed, or they did not have enough servers scheduled. Fortunately we were not in any hurry, and they were very polite (the chef/owner even came out to apologize that one of our dishes went to another table).
We started with chicken liver parfait and the duck breast prosciutto. The parfait was excellent, and the prosciutto was even better, with a watermelon jelly-type thing that nicely complimented the meat. Then we had Billy's squash gratin with thyme (the type of squash changes daily, depening on what looks good to Billy), the soup of the day (which I can't recall the details of, other than that it was very good if a little salty for my taste), Penn Cove oysters, and carpaccio of yellowtail. The squash came in a small (and hot) skillet and had a great texture and flavor. The oysters were about the best I've ever had -- large, just chewy enough, with just the right amount of brininess. And the yellowtail was as good as I've had at any sushi restaurant with an excellent sauce not too heavily applied.
We moved on to the squab and the hangar steak. The squab did not do much for me, but I am generally unimpressed with squab so I'm probably not the best judge. I think you get too little meat out of the thing. The hangar steak, though, was fantastic, charred on the outside, butter-soft on the inside, with tasty green lentils accompanying it. We all loved it so much we got a second order.
For dessert, we shared the Valrhona chocolate cake (perfect) and one other dessert I can't recall but that was equally tasty.
For wine, we had a Patricia Green Chardonnay (from Oregon, $32), and a white Bordeaux. Our friends brought a 1996 Leonetti Merlot, which was outstanding.
The food was excellent and I can't wait to go back. Our server was very knowledgeable about the menu, and helpful in making choices, but she was run ragged with too many table to look after. She almost never checked in to see if everything was okay. Fortunately, it was. This is old news, but let me be the next to give Lark two enthusiastic thumbs up.
