yeah i've been to sonar maybe 3 or 4 times since i moved there....their hiphop/indie/electro/rock nights on friday (taxlo) are halfway decent...though i think mainly because it's $4 pitchers of PBR before 11, heh.
i've also been there during their dnb/techno/whatever nights and its been alright. i just wish i could walk there instead of taking a cab heh. (i live in the canton area)
