If style is a currency, then Retro Inferno is a 10,000-square-foot gold mine. The store is packed full of priceless nuggets of classic 20th century design, from high modernism to art deco to campy space-age chic. Among the finds: a late 1940s desk designed by George Nelson for Herman Miller sporting a blonde finish priced at $2,500, a rare Edward Wormley dining set made from light and dark mahogany for $10,000, and an ultrakitschy sofa that would look perfect on the set of The Jetsons for a mere $550. At any given time, the store stocks well over a thousand pieces, from a little over $100 into the thousands. But one thing you can be sure of: The prices are always lower than you'll find in New York or L.A. In fact, the owner often sells goods to dealers on both coasts for the same prices KC shoppers pay for them, which the dealers consider to be wholesale.
