I've written here before about how much I love my friend Roberto's Fonda restaurants. The original one is in Park Slope, Brooklyn. The second in Manhattan's East Village. And now there's a new one in Chelsea, which it was my good fortune to visit for the first time on a recent trip. Same magnificent food (I had carnitas.) Same cool vibe. And, since word spreads fast, same crowded scene. Here's a look at the guacamole bar with an order of the award-winning guac about to be served.
