Went to the Striphouse (12th Street, right across from Gotham Bar and Grill) for the first time last Sunday with a friend from out of town. Wasn't too crowded, so we were seated immediately. The space is warm and comfortable, sort of dark with a reddish glow, with black-and-white photos of semi-nude early Hollywood starlets on the walls. We ordered simply: Bibb lettuce salads and New York strips, along with a very nice (though expensive) Burgundy. Waiter started us out with little shotglasses of a chestnut soup (tasty). Salad was just OK, lettuce a bit limp. The steak, ordered medium-rare, was more like medium, but I didn't complain, seeing as everything else about it was righta well-seared, well-salted crust, and a marrow-filled bone and Bearnaise sauce on the side. Steak had wonderful texture, tender but not chewy, and would have been perfect if a bit rarer. What made the meal, though,were the sides: black truffle creamed spinach to die for, and "fried potatoes"seasoned whipped potatoes formed into logs and fried to a golden crisp. Service was attentive and personal. Prices are up there, but in league with other quality steak places.
