I had the Hubert Keller burger and the buffalo was surprisingly good.  I wasn't expecting it to be as juicy and flavorful.  My only complaint was that the caramelized onions and blue cheese overwhelmed the burger.  Others at my table had the Kobe beef burger or the Black Angus burger which were good, but not out of this world.  \n\nI would definitely come back to try the buffalo burger again, but would probably opt to build my own and take the less is more philosophy.
