You can tour the only Frank Lloyd Wright–designed skyscraper ever built, the 1956, 221ft Price Tower Arts Center. Inside and out it is like Architectural Digest meets the Jetsons . Wright shopped the design around for 30 years before he found clients willing to build it here. You can even stay in one of 19 Wright-inspired rooms (from $140). The 15th-floor bar, Cooper, has sweeping views of the prairie (fitting for a Wright construction).
