Last time I was in STL was 2 years ago but I ran rampid throughout the local taverns.
Only 3 that I would recommend are....
1. Tequila Wyld.....( might be outta business now but who knows ) . This bar is down laclede's landing. As I remember you can see one of the casino's from the back deck at this place. It's 2 levels and plays mostly rap music. They were bumpin Rap/R&B constantly and there were quite a few females. I didn't realize they had a downstairs until after they closed and I think it played music besides all rap. was a good time with no static in a gangsterous atmosphere. I think they didn't close until 3 but I may have killed those memory cells.
2. Patricks on Westport....... It was pretty cool, My partner was dj'ing there. It had a kind of preppy girl wants to get fucked type of atmosphere. There was always a bachelorette party going on so lots of drunk sluts were all over the place. They call them patricks pachelorettes and I wish I could have poached one from the herd. This was a good time, I think they closed at 1:30 but can't remember. Westport in st. louis is a pretty clean spot. Older people were out gettin thier drink on and it was a static free environment.
3. The Oz on the East side...... My rampage ended at the oz late sunday night or early monday morning around 5 am. I got thrown out for falling asleep on the bar, but what's a fellow to do when your fucked up and lost

. This place was pretty tight from what I remember, It didn't close until 6am monday morning. There was a 50/50 ratio of male to female. I was a little too fucked up to recall all the details but they played a mix of all kinds of music. It seemed that they had a problem with playing too many rap songs in a row because it would start fights. Good time but I'd rather stay in missouri.
just some knowledge from my experiences
