Comments: "In a city where food presentation is elevated into an artform, this store peddles food pornography of the most sordid and explicit kind. I'm surprised the wheels of my chair didn't go rusty from the dribble trailing from my open mouth. From the displays of unbearably beautifully fruit to the softly cascading clouds of dry ice that caressed impeccably fresh fish in dream-like soft-focus, this store is nothing but a delectable series of temptations." -(Loretta) Link, Map.
