Poison Girl’s got a strangely schizo feel to it. Inside, the narrow bar and hipster/rocker clientele reminds you of a dive in Brooklyn’s Williamsburg or San Francisco’s Mission District. Outside, though, the whole vibe shifts Texas-ward. There are picnic tables loaded with glasses of Bock beer, pebbly dirt on the ground, lots of lush subtropical foliage…and the rear of Poison Girl — that peaked white clapboard facade. What does it look like? You can’t quite place it at first, but then it comes in a rush: Gruene Hall. Somehow, even though you’re in the very heart of darkest Montrose, you feel like you’re in the Texas Hill Country. That’s one magic patio, folks.
