The spartan lunch-counter decor looks like it hasn't been updated since the 1960s, and the food is similarly retro - Japanese-style spaghetti served with plastic tubs of potato salad as a side order. The mentaiko spaghetti is a heap of thick, soft-cooked pasta livened up with shiso leaves, shiitake, onions, nori and komatsuna greens nicely balancing the spicy cod roe.
Other options include the Jalico (shrimp and meat), Ume Nori (with a plum-flavored topping), China (featuring zasai pickles), and Kimchi (with pork). Regular portions are reasonably sized, but the jumbo size (for an extra Y150) is almost comically large. Gigantic bottles of Tabasco and tubs of parmesan cheese are available if you want them.
Open until 4pm Saturdays.
