Founded by Kathryn Connor and Lindzi Shanks, XO Marshmallow is Chicago’s first all-marshmallow café and the world’s first “marshmallow café and wonderland.” XO Marshmallow’s mission is to “bring the nostalgia of sipping cocoa with s’mallows, or roasting s’mores by the campfire, into the 21st century with a modern twist.” The A.V. Club was lucky enough to spend some time with Connor in the Chicago café, learn the company’s history, and stuff our faces with marshmallows. Fortunately, you don’t have to fly to the Midwest to have a taste. You can purchase XO’s marshmallows on the company’s website.
