In recent years, pretty much the only place you could spot a beverage cart was in black-and-white movies. But recently, the wheeled, multitrayed carts have been appearing in stores. "Entertaining at home is hot right now, and people have rediscovered beverage carts," says interior designer Chris Breining. Breining notes that built-in bars are also increasing in popularity, but says the wheeled carts offer more versatility. They can take the place of the built-in bar and be just as elegant.
