We will arrive late Saturday night and will spend a night in Ginza. We have to leave for Osaka on Monday. I figured that most of the restaurants will be closed on Sunday, as well as Tsukiji market. The results of my study of Sunday-opened restaurants in Michelin guide were not impressive. So the only idea I have so far is visiting Depachikas.
Please advise any other interesting things to do in Ginza on Sunday for a first time Tokyo visitors.
Bonus question: Where can we eat on Saturday at 11 pm?
