I've been on the hunt for a retro bar cart lately, and was recently tempted by a Lucite one on Craigslist. To be honest, I don't even drink liquor — I prefer vino and Hefeweizen — but I just love the way they look. Admittedly, I also dream about having groovy cocktail parties, serving up spirits to my pals in my growing collection of highball glasses, while doing the twist. I wish I were that cool. Do you have one?
