The "Party World" is located just across the street from the railway station. I wasn't there for ages, but some years ago people would call it "kiddie disco" and many people I knew would rather go to the "New World" in Wildau. You'll find more info's about the New World on my Wildau page.
But in general, I would still recommend to go to Berlin for nightlife. You just have many more options.
This Irish pub was opened in 1994 and if you wanna try some Guinness, Kilkenny, Cider or Whisky and enjoy live music, it's your place ;-)
daily from 19:00 - open end
If they have Friday/Saturday some live music and a band there, the admission will be 5 €.
