My friend once told me he liked the Paradise because it's the only bar downtown that will let you smash a pool cue over another person's head. I haven't seen that happen yet, but I have seen a man's bare buttocks.
That's not why I like the Paradise, though. I like it because it's dark, loud and the only place that will play Prince and Slayer back-to-back on the jukebox.
In a sense, it's a friendly anarchy. You can be completely self-indulgent without worrying about spilling a little of your drink on the carpet. You can take the bar at your own speed without anyone telling you how to drink. You can order food from the bar until well after other bars have covered their stoves. You can basically do whatever you want. Just be careful that in doing so you don't piss off anyone else, because while the large kitchen, billiards and foosball tables make standing room cozy, they also mean a pool cue is never too far out of reach.
