Den Deli pimps bobas and hijikki, a lovely miso soup and a Japanese French dip, sushi and spicy shrimp and udon, soba and, above all, ramen. It arrives in a smoldering bowl of chicken broth, lightly seasoned, and you slurp the noodles with deliberate abandon, making as much noise as possible as they slip through your lips. The noodles drift with bean sprouts, slivers of green onions, wilted bok choy and the Deli's version of tamago, usually a sweet omelet with soy that, in this case, is a soft-boiled egg with a bright yolk that weeps streams of wet gold into the lush broth. And there, lurking below the mound of vegetables and garnishes, are slices of pork belly, our favorite food in the culinary solar system.
