飲み放題/Nomihoudai means “All you can drink”.
All. You. Can. Drink.
This includes soft drinks and alcohol and everything in between.
The price can vary from under 1000 yen to 3 or 4000 yen for premium menus or classy places.
It’s usually 90 minutes or 2 hours of binge drinking.
Paired with tabehoudai… the best thing ever.
