I had a bison steak at Charlie's in Orlando over the summer.  It was good, but I think they overcooked it a tad, it was a bit on the dry side.  Bison burgers are great, I'd have a hard time guessing it was bison if I wasn't looking for a different taste.  There's a Bison farm in the next county over, they sell to a lot of area restaurants, they ship too:
