Add a touch of vintage glamour to your kitchen with a built-in margarita machine. Choose retro-inspired appliances in pastel colors, like mint green or baby pink. Install a marble or granite countertop for a luxurious feel. Hang a vintage chandelier or pendant lights above the bar area. Display your collection of vintage cocktail glasses and shakers on a bar cart or glass cabinet. This kitchen decor idea will transport you back to the glamorous era of the 1950s.
