Meh.. I never loved this place. A little over priced, and over hyped.
Then I read this fascinating article on the great Kobe Beef lie, and realized M:Brgr is one of the culprits, advertising "Kobe patties" on their $100 burger.
Firstly, it's IMPOSSIBLE to get Kobe beef outside of Japan. Secondly, even if you could, why on earth would you grind that cut of meat into a patty?
