"Though Dallas’s downtown skyline has evolved over the last decades, as more gleaming, angular towers have been added to the mix, you’ll still always know you’re looking at the Big D thanks to one iconic structure. Dubbed The Ball, the dome-topped Reunion Tower is a 561-foot observation structure that opened in 1978, along with the adjacent Hyatt Regency Dallas. Renovated in 2008, the tower now featuresa 68-second elevator ride up to the GeO-Deck observation floor, where interactive screens, high-def cameras, telescopes, and indoor/outdoor areas all showcase the 360-degree city views from 470 feet up. There’s also the casual Cloud Nine Café on the same deck, as well as celebrity chef Wolfgang Puck’s Five Sixty higher up. The latter has separate areas for fine dining and slightly more casual meals, as well as two glass-fronted bars—one rotating, one stationary—that serve an impressive wine and sake selection along with the incredible views. At night, the whole dome is lit up with hundreds of LED light fixtures, making for an even more special experience."
