Gyokotsuya Ginza is a late-night ramen shop in Ginza, Tokyo, serving sea bream bone broth ramen and tsukemen. Its signature dish is a fish bone ramen with a rich sea bream bone broth topped with cabbage, shrimp tempura crumbs, and seaweed. The shop is open from 9 p.m. to 4 a.m. the next day, and the kitchen and restroom are kept clean. The broth is divisive because of the fish aroma from the sea bream bones.
