Walk by Poison Girl fast enough and you might not even notice it's a bar. That's because the giant outdoor sign that says "Cocktails" is actually inside this Westheimer watering hole, which is celebrating its tenth anniversary this year. (Salud!) That sign is just one of the many quirks that make Poison Girl one of Houston's favorite drinking establishments, along with the amber whiskey bottles, pinball machines, R-rated velvet painting straight out of Dolomite's private collection, and the giant Kool-Aid Man out back. Poison Girl is always a happening place, but some nights it has more character than others — Monday nights, local personalities come in to DJ or simpatico local musicians might stop by to play one of the bar's "Tiny Concerts."
