I'm on a crazy oyster binge. Suddenly can't get enough of 'em. I recently got back from NYC where I spent a couple of hours sampling some of the dozens of different varieties at the Oyster Bar in Grand Central Station. I'm desperate to find a similar experience in LA, preferably somewhere where I can knock back an icy martini or two while assessing the differences between Discovery Bay and Fanny Bay, Blue Point and Shinnecock. The closest I've come so far is McCormick and Schmick, a very pale imitation. I'd love to find somewhere in Hollywood. Ideas?
