Like Palác Akropolis, the Roxy is a former theater that's carved a niche as a leading venue for live performances of techno, electronic music, and other alternative sounds (though mainstream acts like a recent performance by Morcheeba occasionally perform here too). Note that the interior is small and shows can get crowded and feel very cramped. Most weeks see several nights of shows, so check the website to find if something is on during your stay. On off nights, there's usually a DJ. Buy tickets at the box office or through Ticketpro ( ). There's a cafe upstairs that shares the same alternative vibe.
