Like Coins Bar, everything you need to know about 300 Bar is in the name. Though it’s situated in the typically high-end suburb of Ginza, 300 Bar is one of the cheapest bars you’ll find in the whole city. Here at 300, all drinks, cocktails, and food cost an incredible 300 yen (US$3) (plus a tiny sales tax). And with no cover charge, it’s arguably the cheapest night out in Tokyo. The way it works is you buy drink tickets and exchange them for anything on the menu. Meaning that it’s less likely for you to lose your wallet or drop all your cash after you’ve had a few.
