I too have sought out consistent, quality ribs in Louisville, and have come up empty.
So I have nothing of value to add, but I share your pain, Jim.
I HAVE enjoyed well-prepared ribs at a couple of places, but in each instance, the next time I returned, back the product was highly variable. Sometimes even the rubs/seasoning seem drastically different..
Given the timing issues, I have pretty much given up on finding consistently high-quality ribs.
I will say that I had extremely passable ribs at the Moe-licious food truck last summer, but it was only once, and given past experiences with various places, I am hesitant to make any recommendations. I do plan on trying them again soon when they return to st. matthews in the next couple weeks.
If you find a place, please let the forum know.
