I Love Sushi is OK. Not bad, but really just ok. I've had so many people tell me its so good and...eh. I was totally underwhelmed when I went. It's definitely a cute place, and their menu is huge. But the menu items aren't that different from each other. I found myself flipping the menu over a bunch to see what the difference between a couple rolls were.
I think it would be good if you are going with a large group and you're more concerned with having fun than eating awesome sushi.
