You rank BK as worse than McDonald's? I only ask cause I've worked at both, and I would put McDonald's just the tiniest bit lower than BK. Wendy's is barely better than both BK and McDonald's.
McD fries are too soft and when they get cold they are absolute garbage. They almost seem soggy, without getting wet. BK have a crunch to them. At least this is the case in the UK.
Not going to say they're good, but it is wild as fuck how much of a difference franchises can make. There are several BKs in my city, but a select few are owned by a different franchise than the majority of the others. Their food is WAY better, consistently, than the others, and it's usually a lot fresher tasting.
I sent my sister a bottle of fry sauce that she's been trying to find for years (she never thought to check Amazon lol), this is what she sends me back. Told her she was supposed to use it to enhance good food, not make terrible food tolerable.
