If you want to have a proper Kobe A5 experience, look no further than Miyabi.
Ordered the set for 2 and a sirloin cut, along with a set of 3 of beef sushi, and we were not disappointed. My 10 year old son, ever the picky eater, rated it a perfect 10/10, closing his eyes and muttered "i feel like I'm in heaven".
Will come back again, hopefully sooner than later.
