When I'm feeling like indulging in the decadence that is Southern Cuisine, I go to Triple Crown.
You can't go wrong with the Meat & Threes. I've had just about every single combination possible and tasted every main meat dish and side dish.
My solid go to is the Brisket + hush puppies + Sweet potatoes + biscuit (although if I had a god damn spine and didn't care about being judged I would go 3x hush puppies, YES THEY ARE THAT GOOD)
The Big Nasty is also dear to my heart (but not my arteries) couple it with some hush puppies and you're golden.
Lastly, pay attention to the specials, if the meat loaf is available, DO NOT HESITATE AND TAKE IT!
