If you happen to like pizza buffets, I recommend Mazzio's. There are multiple locations in the Tulsa area. Kim and I have been guilty of over-eating there many times.
Dan Hetser's rumor has it that Shortbus is somewhat an expert on buffets, so you might want to check with Bill. And if you don't want to talk about food, I assure that conversing at the Chili Bowl with Bill and Lloyd about racing is fun, too!!
Damn! I'm gonna miss it this year, and I had not really regretted it until this thread.
