there is an institution in japan called "nomihodai".
this means "all you can drink". it's very popular with young people. you pay usually about 20 bucks and get an hour or two of continuous beer, cocktails, whisky, nihonshu etc. the cocktails are just syrup mixes with soda of course. but you used to get a full bottle of whisky if you asked - recently just one glass at a time.
the interesting point is that it is often written as "free drink" in english. while i can understand free drink as the general "nomihodai" concept, when it comes to the menu that says "free drinks" it starts to sound like i don't have to pay at all.
