Finally found time to try this! The beef Don comes in a set, with sesame tofu as starters, miso soup and an onsen egg which the Chef recommended me to pour over the beef slices. He first caramelises and sears the beef with sugar and other sauces, thus making it oh so sweet before putting in the other ingredients like tofu, mushrooms and shirataki noodles. Decided to be less adventurous and went for the cheaper option first, definitely trying the premium one on my next visit!
