Fast casual has stormed the QSR 50 in the last few years, with Panera Bread entering the top 10 and Chipotle close at its heels. That trend continued in 2015; Panera and Chipotle each padded their sales, with the latter leap-frogging both Sonic and KFC in the rankings. (Of course, Chipotle’s food-safety woes struck at the end of 2015, a sales hit that will likely be reflected in next year’s QSR 50). Elsewhere in fast casual, a pair of sandwich chains—Jersey Mike’s and Firehouse Subs—continued their incredible momentum up the list, while Wingstop similarly managed to jump multiple spots in the rankings.
Meanwhile, legacy quick-service chains were a mixed bag in 2015. McDonald’s finally found its footing after years of disappointing sales returns, and Taco Bell managed to jump Wendy’s and solidify a spot in the QSR 50’s top five. But KFC ceded more ground in the chicken wars, slipping to spot No. 14 overall—only six spots and just over $1 billion in sales ahead of Popeyes, which enjoyed a major boost in 2015.
