While the humble DiDi Deli serves unexpectedly good chicken salad sandwiches and cheeseburgers, its Korean menu really steals the show. The Korean barbecue, for example, is nutty in flavor, tender and a little sweet. Bi bim bop
-- a useful yardstick for measuring Korean food -- is a traditional dish of mild barbecued beef, fresh bean sprouts, lettuce, mushrooms, shredded cucumber, sliced zucchini, stewed greens and a fried egg, all kept separate but piled on a big mound of white rice, served with go choo jong,
a thick, heavy, red-pepper paste you can use to your liking; DiDi's version is impeccable, with an ideal blend of textures, tastes and temperatures.
