For the second time in just over a year, Popeyes has mysteriously gone dark for several weeks at Westfield Montgomery mall. Last time, when the restaurant finally reopened, employees vaguely blamed the closing on “the kitchen” and “the fryer.” This time, we’re hearing the departure will be permanent. Meanwhile: Just around the corner, another New Orleans-style fast food chain is on the way to the Dining Terrace. Kelly’s Cajun Grill, specializing in bourbon chicken, is taking over the space next to Panda Express.
