This down-the-rabbithole music club near Mały Rynek has a slightly scruffy, dive disposition, but that's the appeal (for us, anyway). Descend the stairs, then more stairs, to find several stages and dance areas where a wide variety of concerts and DJ sets take place throughout the week - everything from rock and blues concerts to ear-shattering techno, electronic and drum&bass sounds. The super-friendly international bar staff contribute immensely to the atmosphere, and depending on the evening you might find a laid-back ex-pat music-and-brewze session, or a sweaty, writhing student sexpit; check their FB page for the forecast. Upstairs and just off the street they also have a separate bar offering cocktails.
