They have a bouncer on Fridays and Saturdays now for the weekend, and Tuesdays cause it's league night. It's probably changed a lot since you've been there. They added a seating area and a whole mess of TVs in the last couple years or so. Football season's good there.
I don't think there's a gang problem there anymore. Fights are mostly between drunk dudes somewhere around 12-2AM usually. But, if you're not a dick, you should be fine. Last one I saw was a guy that brought liquor in and they cut him off and told him to get out. The bouncer and another guy made sure he did. By the way they now have a facebook page.
