If you want an authentic Japanese foodie experience then we implore you to go to Japan. If that’s not possible, stay in London and head to Matsuri. The official restaurant for Japanese delegates and athletes during the London 2012 Olympics, it comes recommended thanks to its teppanyaki style dining.
Secure a seat at the counter and watch as chefs slice, grill, skewer and kill (maybe not kill) your food in front of you. If you like dining to be a spectacle then Matsuri is as good as it gets without heading to Proud Cabaret
for your food.
