A look through the welcoming window of the Christkindlmarket stuffed gourmet pretzel stand in downtown Chicago, Illinois. A baker creates more delectable twists of pillowy dough to add to the rapidly growing tower behind them. The ambience is warm, like a hug. Outside the stand, a sign lists the variety of flavors offered: grilled cheese, spinach feta, traditional bavarian, pizza, jalapeño, and cheesecake.
