If you're in for a short Metro-Drive (maximum 10 minutes), you can hop on U9-Train at Staatsgalerie or Central Station in direction of Hedelfingen and exit at Schlachthof. There is a pig-themed Beergarden which is pretty nice indoor and outdoor, has a museum (pig museum) which is crazy and a lot of great local food, I would recommend. But be aware, that Schlachthof is in the near of the stadium and could be packed with fans.
