Usagi is a ramen shop near Shinsen Station on the edge of Shibuya, serving tan tan men and ramen. The menu includes chicken broth ramen, tan tan men, tan tan tsukemen, and a brothless tan tan men, with truffle shoyu ramen as a special. On a Thursday at 11:35 a.m., four parties were in line, with about 20 minutes to enter and about 5 minutes until the food arrived. The shop is small, so waits occur.
