Party Boy, located right off I-10, is our favorite party supply destination. The warehouse is chock-full of balloons, goody bag stuffers, patterned plates and cups, customizable banners and more — and the ready-to-help staff will guide you through the expansive space. Since 1985, it has also been a year-round destination for costumes, so you're covered even if Halloween isn't right around the corner. It even has themed party supplies in case you want to hold a Western or disco party (or, heck, a Western disco party). Plus, you can rent a popcorn machine, sno-cone maker and other food service equipment. If you want to just make one stop for all your party supplies, Party Boy is your answer.
