For the longest time I thought I didn't like or outright hated BBQ food because almost every time I tried it, it was either mediocre or just flat out awful. The meats that these restaurants would pride themselves on just tasted like smoke and not much else. Sometimes the sides would be good, but a lot of times the sides would be awful too.
Turns out, BBQ isn't inherently awful. I've had good BBQ before, but it's vastly outnumbered by all the bad BBQ restaurants out there.
