Wigwam is a nice place to hang out... but be aware that in this place the bouncers are the far most notorious troublemakers. I used to be resident in Budapest and spent a lots of times in that venue so I know if they just don't like you they beat you up even you haven't done anything wrong. Like they hunted for prey every night - honestly..
During a regular night without concert you can have some soft/glime rubbish. DJ never puts the song in you request unless you have boobs and smile nicely.
Concerts can be anything there from soft rock to death metal. It depends.
Altogether it's a nice place if DJ has a good day but be careful there.
