For a good take on the lay of the land, just circle the eight panoramic panels on the observation deck of the Tower of the Americas. The 750-foot-high tower was built for the HemisFair in 1968. The deck sits at the equivalent of 59 stories and is lit for spectacular night viewing. The tower also hosts a rotating restaurant with surprisingly decent food (for the revolving genre) as well as a thankfully stationary cocktail lounge.
