Food under delivered, especially for the price. Drinks were good, ambiance was good, food was average. We were told that the 18% service charge doesn't make it into the hands of the servers, so we ended up tipping an additional 20% on top, which made for an expensive average meal. So now we're wondering if we were misled by our server or if the restaurant is one of many accused of this practice. Neither is a particularly good case. UPDATE: the restaurant called to apologize and refunded the additional tip. Much appreciated.
