I've never been to Mr. Bunky's although I've heard good things.
Maurice's seems to be the most well known Columbia BBQ place but there are lots of others. We're lucky to have a great selection of BBQ types here. Within a few miles we can get mustard based (my favorite), NC style tomato based and vinegar based.
Cola. can get hot and humid but you learn to live with it. I love it here.
