Downtown’s Treehouse craft cocktail bar has been in business for about four years now, but the cozy space is getting an upgrade. This week, the bar re-debuts after a remodel that expands it into “the space next door,” which means dance club the Attic. Owners Orlando Bar Group say that the Attic will be trading some of its space with the Treehouse to satisfy demand throughout the week. Treehouse’s schedule is also expanding to Wednesday through Sunday. But the best news? The expansion includes plenty of astroturf.
