World's Fair Donuts

World’s Fair Donuts is unapologetically old-school. The beloved Southwest Garden doughnut shop still takes only cash. (Signs inside remind you of both the policy and its wisdom.) Not that you need much money for World Fair’s heavenly yeast doughnuts or its buttermilk cake variety, the shop’s signature selection. World’s Fair Donuts doesn’t see the need to use Twitter or to reinvent itself every week or clamor to remind us that it does, in fact, exist. Owners Terry and Peggy Clanton are too busy opening up the shop at 4 a.m., pouring coffee and making great doughnuts.
