Oak Cafe is located in the heart of the old-fashioned Iroha Yokocho. Typical of authentic yokocho establishments, it is small and intimate, with space for just six customers at a time. It serves delicious vegan lunches based on macrobiotic principles. The menu consists of two options: a bean curry or the plate lunch. The contents of the plate lunch are rotated daily but always consist of sprouted brown rice, miso soup, and an assortment of six or so macrobiotic protein and vegetable dishes. It is also one of the few indie dining establishments in Sendai to offer breakfast.
