My wife and I stumbled into this place after not wanting to blow $600 at Per Se or Masa to celebrate our 3-year wedding anniversary. Boy were we both pleasantly surprised. The steak -- she had the tenderloin for one -- was perfectly cooked. I opted for the duck steak, which got a nod from the waiter. Turns out, the duck is big hit for the price. Our entire meal, with tip, came out to less than $250. We each had an appetizer, the shrimp cocktail -- massive -- and, the seared scallops -- also delish. We also tried some sides, french fries, onion rings and brussel sprouts. The fries were good but not of them were necessary.
They really have their act together on the service at this place. The apps came out quick, followed by entree. We were too stuffed for dessert, though it looked great.
Definitely worth a trip, especially for an occasion.
