At $4.19 per side, KFC's mac and cheese is a decent value, but the portion size is small and it tastes bland and weirdly artificial, leaving a fake aftertaste.
At first glance, Church's Texas Chicken Mac and Cheese looks cheesy and creamy, but after a few bites, it turns out to just be covered in congealed, tasteless cheese.
Popeyes' mac and cheese lacks the prominent artificial flavor that KFC and Church's have, and has a better cheese flavor and a creamy sauce, but it's still not great.
Noodles & Company's mac and cheese is creamy, has a fantastic flavor, and the noodles are cooked to the ideal al dente texture. However, it's a bit bland.
