Leo's and Vans pig Stand are the best hands down everything else is commercial crap.
I hear Rudy's is good but i have been in there yet.
The one thing i will give Earls is they hands down have one of the best hamburgers ever made with the Cheddar Burger.
You could also just shoot over to Ponca City and eat Head Country. You cant go wrong with Jack Daniels Grand champion winner.
Vans is tops in my book, Shawnee, Norman and Moore locations. I prefer the Norman store but they are all good. My normal order when I am out with the kids and wife is a side of ribs, family fries and a sliced brisket sammich. Feeds the whole crew of 2+5. Good people to boot and Jev is a member here. I just bought a gallon of there hot sauce and three pints of mild to use on my home smoked meat.
Leo's would be my first choice. Van's in Norman is usually ok. GFF in Moore surprisingly has good barbeque. You could show them how our grocery stores have better barbeque being smoked in a shed beats anything coming out of that state lol.
