The Best Restaurant in The Seaport, South Boston, and East Boston, Boston

Let your nose lead you here on a Saturday night, but expect to wait in a massive line of foodies looking to get their hands on one of four award-winning niku udon noodle dishes (cold or hot, and spicy versions of each) topped with sweet and savory beef. The restaurant itself is absolutely tiny, but its local reputation is huge. For a scratch-made quick bite that's truly unique, this is a must-stop.
