Ginza Oborozuki is a tsukemen shop in a small alley near Ginza Five in Tokyo. Its signature dish is tsukemen, thick firm noodles dipped into a rich broth with a strong katsuobushi aroma. Waits are common, with one case of a 30-minute wait, and a line sometimes forms before opening. The shop has only six or seven seats, so storing a suitcase is difficult and turnover tends to be slow.
