If the name didn't do it, the oversized photo of buckwheat fields would clue you in: noodles are the thing at Soba Nippon. In truth, I'm partial to their udon, slippery smooth noodles with an al dente bite, served cold or in a hot bonito-and-kelp broth. Shown at top are the simplest, Sanuki-style version ($11).
On another occasion, I ordered the soba, a housemade blend of 20 percent wheat and 80 percent buckwheat, with tororo, or grated yam ($15). The noodles themselves were thin, delicate, and darker-hued than the udon; the yam, which looked like a puddle of grated Parmesan in the center of the bowl, had a slippery yet grainy texture and not much flavor. That broth, on the other hand, I drained to the last few drops.
On another, brutally hot summer day, a cold beef soba salad (bottom photo; $19.80) filled a large plate with noodles, lettuce, carrots, onions (on request), plus a little seaweed, topped with two tender, thin slices of lightly cooked beef, sesame seeds, and a nice, somewhat vinegary dressing. An expensive lunchtime salad, but big and satisfying without being overwhelming.
