Top-notch soba in the East Village. You can just get the classic Zaru Soba and you'll probably be happy, but I recommend getting one of the (cold soba) specials instead. I got my soba with soft shell crab and the taste of the shellfish definitely enhanced my soba experience. And if you're in the East Village early, they have a prix fixe menu available until 7 pm every night.
