Actually, buffalo burgers can be pretty good. Also, I believe I greatly enjoyed an ostrich burger when I was younger. I think both can be found in places in the Midwest (I know buffalo is big around Yellowstone National Park).
I am not a vegetarian but I think burgers are just unappetizing. Its like how alot of people who happen to not be vegetarians don't like fish .
True story. But when I use to like burgers (When I was 7) I would definitely have to go with Five Guys. But now I can't be within 10 feet of a burger.
