Yoshi's is a sweet little place in Powderhouse Square, Somerville (a short walk from Davis). They have an excellent lunch box which I think is the best value for lunch in the area. For $7.00 or so you get: an entree (tofu, tempura, salmon, beef, etc.), dumplings, salad, maki, seaweed salad, lettuce salad, miso soup, etc. Can be done all veg as well! Always fresh and tasty, clean decor, very pleasant service. Great neighborhood place.
