Every month the Randolph Street Market Festival offers Chicago locals the opportunity to browse the stalls and shop for everything from antiques, to home decor, to gourmet food, to global arts and crafts. The next festival date is scheduled for October 26, so mark it on your calendar today. You'll be able to explore more than 125 vendor booths, including plenty of autumn- and Halloween-themed shops selling costumes and other seasonal items. You'll also find local artisans selling hand-made jewelry and artwork, as well as plenty of on-site food trucks serving up tasty treats.
You should be aware that this is a ticketed event, and to receive the discounted price you'll want to purchase your tickets online before you go ($8 for general admission, kids enter for free). The website also includes a variety of other ticket options, including food and drink packages, season passes, and more.
