Poker Night at Jack's. Jack's Backyard is located just South of downtown Dallas in Oak Cliff. It is a mixed crowd, but predominantly Lesbian. A retro renovated garage and patio space, two areas for entertainment- inside the garage and outside a larger stage. urban and minimal decor inside, full bar, and a relaxed, laid back environment. Dog-friendly and nice bathrooms. Often times valet. A chilled out Lesbian scene.
