buffalo burgers are everywhere around here (Alberta, Canada), and it's cheap... funny how that works, we pay much more for stuff like steaks, roasts and brisket up here, but the more rare stuff we pay less. I think its because of the Alberta beef hype train... which is a bunch of crap. I have had good and bad beef from both sides of the border.
As for the buffalo... you will be much happier if you throw some sausage in with it, it is a lean meat.
Now if you want to try some really tasty meat, try to get your hands on some cougar! Oh man, cut it into strips, bread it and throw it in some oil in a pan and you have yourself a little piece of heaven.
