Does Sizzler count as fast food because I can't remember ever running so fast to the bathroom after I ate them. I'm glad they more or less went belly up
But IMO worst fast food Joints are
Burger King (Whopper is the only edible burger in their lineup, worst fries of any fast food chain even when they are hot they taste cold)
McDonalds (Cannot find the balance between quality and price even their upscale stuff is nothing to call home about Fish Sandwich should be a dollar menu item stopped eating their breakfast after they dropped the Steak and egg breakfast burrito about 2013 maybe)
Subway (5 dollar footlongs made them the king, the Jared scandel killed them and they never recovered worse yet, most of these places run by Indians with 'questionable' hygiene at least in NJ/NY. No real meat on their menu even the chicken is mostly soy)
Sonic (Bloated menu basically means you won't get anything fresh, only thing they have going for it are she cheap slushes and shakes)
KFC (Everything tastes like a salt lick, chicken is almost never fresh, warm cole slaw, mashed pototoes are OK, Wedges would be great if they were fresh)
I've been all over the South, Bojangles isn't perfect but I would take them over Popeyes and KFC. But I could also understand they won't compete with a small homade joint either.
