My wife and I had a superb meal at Katsu last night, sitting as the sushi counter and chatting with Katsu. The highlights:
Agedashi with eggplant: the traditional dish, but with eggplant strips instead of tofu. Added yet another flavor to a great dish.
Premium yellowtail sushi: I don't know what "premium" means, but these slabs of yellowtail were a different food from the normal stuff.
Softshell crab with avocado wrapped in deep fried Yuba skin: As Katsu explained, this gives you a crunchy outside and a creamy inside.
Grilled premium yellowtail jaw: grilled with salt, and eaten with a squeeze of lemon, grated daikon and dipped in soy.
