536 N. Fourth Ave.
One of the first stops to make while heading down Historic North Fourth Avenue, Sky Bar may stop you from making it much further down the avenue. While the live music and the fun atmosphere at Tucson's only solar-powered astronomy bar and café may draw you in, the cocktail menu boasts some of "the best drinks in the universe." Try the Solar Smash if you're looking for something really out of this world.
