Just as an fyi: Another option may be the "Stadion an der Schleissheimer Strasse", a well known football-pub.

Reservation recommended, since all scheduled German games, the opening game and Netherlands-Spain are fully booked. They do offer some "first come-first serve"-seats for every game, but these are only a few ...

It is, imho, one of the best football-pubs in Germany!
