For what it's worth, my wife and I have found that public rating, such as yelp and the like, are a terrible way to find good restaurants. The number 1 rated restaurant in Louisville was terrible all three times we went there. Lower rates ones were spectacular. I'd call them regional "destination" restaurants in fact.
Caustic… ever been to Heirloom in Midway? Pretty neat little town, good restaurant and a nifty tailor at the end of the block called Crittenden. I suppose it's closer to Lexington than Louisville, but worth a day trip.
