Add to that, Yum Corporation
http://www.yum.com/company/our-brands/ who runs KFC, Pizza Hut, and Taco Bell, overall bad experiences. Pizza Hut left Greenbriar years ago when its service went downhill, and own experience and online reviews do not speak well of KFC in Chantilly
https://www.yelp.com/biz/kfc-chantilly?osq=KFC most reviews negative with sample 'I don't normally like to review chain restaurants, but this is definitely one of the worst places I've ever been. The employees here are incredibly, INCREDIBLY rude, uncaring, unkind, uninterested, and unhappy. I like to give people the benefit of the doubt, but the service here for the past 2 visits has been the same: consistently unpleasant. Orders are always wrong...Food quality is also incredibly poor here.' It seems Yum is another corporation more concerned with its stockholders than its customers or employees.
