My friend's dad opened a Japanese near the Macy's at the Shops on Lake plaza in Pasadena a few months ago. I've eaten there more than a few times and am quite pleased with their consistency. The decor is modern and attractive. They have your usual suspects: bento boxes, rolls, nigiri sushi etc. They also have a special section of their fusion dishes. There was a "Japanese Pasta" which I was hesistant to try at first but is now one of my favorites. It's an udon dish with a spicy, kinda creamy tomato sauce with shrimp, asparagus, and other veggies. Quite tasty I must say. A con for the restaurant is it's location. It's a little hidden (between the Corner Bakery and Macy's) and cannot be seen from the street. Anyway, I would recommend this place because I enjoy their food and the service is pleasant so I decided to try and help get some word out there for Hanabi!
Oh, and another note. I had their Galbi (Korean short ribs) the other day and those were quite good as well!
