Thank you! I was looking for late night eats for my similar layover this week, I guess Shinjuku is the best place for that for late arrival into the city after 11pm?
Also, is Sushi Ten only for 2+ people? I see on the reservation form there's no single person input.
There are late-night spots in Shibuya and Marunouchi and other parts of town as well, with varying degrees of tourist-friendliness Actually the west side of Shinjuku is relatively early compared to the east side, but there are a few places. (And sorry I don't know what Sushi Ten's reservation policy is.)
