I've been over here for a few months and have been amazed at the creativity that chefs here employ when it comes completely destroying a dish--never terrible the same way twice. It's high comedy that is slowly turning to tragedy. But I can't believe that everything here is inedible. Though I'm learning that everything is absurdly expensive (and I'm coming from New York). Anyway, enough griping. San Francisco has burritos, New York had Shopsins, LA has Mexican food and Korean BBQ and Langer’s pastrami and well, a lot of things. But I’m hoping you all can help me figure out what London has. What is that one exceptional thing you can get here that just isn’t the same anywhere else, and where does one find it?
