and the belgiums drink even more beer than we germans. (shame on us, but then some of the belgium beer, nobody would call a beer in good ol' germany
)
Yeah i meant half a liter.. approx. a pint if that helps you. just a tad more.
oh you can drink anything you like in frankfurt. the state in which frankfurt is, is called "Hessen" and every true Hessian tell you that the only Drink there is is "Äppler" its also nickedname "Gödderdrobbe" which is in the Hessian akzent and translates as much as "Drink of the Gods". Its also cheaper than beer and has more alcohol ('prox double the %) and sometimes you mix it with lemonade ( a "sweet" äppler) soda water ("sour") or coke ("Korea").
You should probably try the sweet version first, because its got a very distinctive tang to it which to anyone drinking it for the first time can be something to get used to, also to a "non hessian stomach" it will make itself noticeable the next day, just a like a good chilli... it stings when it goes in, and it burns when it goes out
and a normal drinking evening in "sachsenhausen" which is frankfurt's pub district would be like this: meet up frankfurt city center, buy a small barrel of beer (5 liters) drink that plus some mead, some äppler some wine, then go to the pub drink some (the damage will be round 10-15€) when the pubs closes at 2-3 a.m. go to the next pub which closes round 5 am and the slouch off to a healthy mcdonalds breakfast
