h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

for example there is the Sausalitos. Half a litre of Caipi for 5 Euro(!!!) between 5 and 8pm. Well, not really nightlife, but there are more than enough alternatives...

Yes, the Sausalitos is a good Tex-Mex-Bar, if you´re out for a lot of drinking!! Good atmosphere there, too! And the Cinema, quite next door to it, is a huge film theatre which often features english movies.

Unfortunate that this is such an old posting but it begs to be updated.
Karaoke at Evergreens is a must. http://www.disco-evergreen.de/
Olive at the Irish Pub down a ways from the train station is a lovely addition to any evening.
And Billy's (next to Sausalito's ) is the local ballet. Do your part to support the art scene. Small bills are a must, change can be found at the bar.
La Toscana for Italian food. (across, and a street back from the McDonalds)
Steakbrot at Zirbel (a local's favorite). Walk out of Las Toscana and turn left. You'll trip over it.

I'm not living in Munich anymore.
But maybe, sometime...
