Yoshinoya Shinjuku Keio mall

Yoshinoya Shinjuku Keio Mall is a Japanese chain restaurant in the Keio Mall passage at Shinjuku Station that serves gyudon. Many customers come for its signature gyudon as a breakfast meal, ordering through tablets or kiosks. Seating is centered on one-person-per-seat counter tables, and food comes out relatively quickly. It can be full even at late hours, so there may be a wait.
