Uosan Sakaba

This oldschool izakaya is crawling distance from Monzen-Nakacho Station, and has been in business since 1954. The first and second floors both have a horseshoe-shaped counter, which is reserved for customers alone or in pairs; if you're a group of three or more, you'll immediately be redirected to a table on the third or fourth floor. Seafood is the name of the game here, and with that golden combination of lots of variety, good taste and reasonable prices, there's rarely not a queue here.
