I’ve heard of people ordering “extra holy” but I’ve not tried it myself.Big fan of Nashville Hot Chicken here. As someone who goes to Nashville on a pretty regular basis, I find that most places dont get it right though. Ive tried the KFC Nashville Hot and its OK but its not the same.
Theres a local chain here in Columbus called, "Hot Chicken Takeover" and their's is pretty close but the spice level is still not like it is in Nashville. You pretty much have to get the hottest spice level they offer and even then, its still a medium spice level in Nashville.
