The Secret Restaurant in Shibuya

Matt was at a British pub in Shibuya when he ordered bang as a mash. Chef came out with a smirk on his face, turned to the waiter and went, no, sausages. They were buying the chicken from KFC? It's amazing, isn't it? So they weren't even cooking the food. This is insane. I do want to find this place there. Matt, if you know the name of this place, please divulge the secret restaurant with us.
