In addition to the typical selection of sashimi, grilled fish and other izakaya fare, Tenmamichi also offers a nice variety of kushiage (deep-fried skewers of seafood, vegetables and meats) and oden (stewed fishcakes in broth). But the real lure here is the sake list, where you can find unusual brews from small craft brewers around the country, often from small batches that never make it to retail liquor shops.
The large basement dining area is stylishly decorated, with a big counter, comfortable little nooks, and tatami seating for larger parties. Budget around Y3000-5000 for ample food and drink.
