Yamachan is an all-you-can-drink premium sake bar located near Shinjuku. For an affordable price you can drink as much sake as you like. You can even take along food and other alcohol with you, or you can leave in the middle of your drinking session and return to order more items. The setting is like that of a classroom, with cheap wooden desks and chairs, and there are no decorative elements. The only objective here is to drink the best sake in the country. The bar is self-service so come prepared to pour your own drink.
