This multilevel club in the Montrose area serves as both a raucous dance club and relaxing patio lounge.. In Short No need to clubhop with Bartini's varied atmospheres. Downstairs, 20-something singles crowd the dance floor buoyed by throbbing dance music and laser light shows. Two well-stocked bars serve up nightly drink specials. Tables and chairs on the downstairs patio provide for people-watching along Westheimer. But it's a different scene altogether upstairs, with expansive windows providing views of downtown. The bar serves frozen drinks and cigars suited to the relaxed lounge scene.
