Shizen's Chicken or Pork Katsu are one of the best ive had. Been having it 5 times and the consistency is good albeit with some changes.
The katsu cooked perfectly, with a batter/coating thats nice, simple and isn't complicated. They include you miso and rice. You cant mess up miso and rice which they dont.
Sauces are pretty good, however the side stuff does change. I went from shaved vegetables to a salad which i personally dont like.
Give them a try. They're pretty solid and quick.
