Epic tonkatsu at a spot called Tonki near Meguro station. You walk in and the space is decorated with raw wood everywhere. There's a wide open kitchen where you see about 6 people working on service, cooking, cutting, and it's amazing. The katsu is cooked per order so once you sit, you'll be waiting, but the wait is worth it. It's perfect all around. You put just a tiny bit of sauce at a time instead of just pouring it all over. I guess it's no secret, I'm in Tokyo at the moment.
