Nomihodai

From WikiJET, the interactive website for the JET Programme

Nomihodai (飲み放題, nomihōdai^?) is an "all-you-can-drink" option at some clubs, restaurants, nomiya-san, and most karaoke establishments throughout Japan. Usually geared towards university students, it is normally only found in big cities. Usually a 2 hour drinking fest will cost about 2000 yen. Beer or wine is sometimes not included - mixed drinks and cocktails abound. Many places have coupons, specials, and other discounts that are helpful when planning get-togethers. Also, there is usually a discount for off-peak hours. This is a great way to have fun and not go broke, especially when out with friends for hours on end.
