Pim Fitt does two unusual things at Yummy Yummy Tasty Thai. First, she'll occasionally tour customers through her kitchen, showing how the dumplings are crimped, how the spring rolls are rolled. And second, with the exception of the pad thai, nothing her kitchen makes tastes like any Thai food you've tasted before. Odds are good she'll have something knocking around the periphery of her menu that you've never even heard of before but that still belongs to the canon of authentic Thai cuisine. The batter-fried spinach leaves, for example, dipped in sweet Thai peanut sauce. We'd never heard of anyone deep-frying a spinach leaf. And yet here comes Fitt, deep-frying spinach leaves as if it were the most normal thing in the world. And after just one taste, we had to wonder why no one had thought of it before.
