Guten Tag!
i just found out, I have tickets for some World Cup games! Of course my first thought was: what am I going to drink there?
Can anyone tell me if I can expect to find mixed drinks most places? I really don't want to drink beer.
Do they have Diet Red Bull there? Is it common? How do you say "club soda" or "seltzer" there? Vodka and mineral water, maybe?

I am sure I'm going to have a lot of questions in the near future. I am going to check out that German forum listed above, but may want to ask some advice for useful phrases that aren't in any guidebooks..."is that breaded?" "Is there sugar in that?"

I took some German in high school. I sure hope it comes back to me.

on edit: I went to atkinsforum.de and found this:

Daheim mach ich mir auch manchmal Wodka-Red Bull Sugar Free. Hat keine Kohlehydrate und schmeckt lecker

so there's one question answered already!
