This restaurant may have changed hands a year or so ago, but it now boasts the best sushi in the western suburbs. The only better sushi I've had in the Chicago region is Sakuma's in Streamwood.
I've eaten sushi all over the world, including tiny places in the Tsukidji area of Tokyo, and this is undoubtedly one of the best in this area.
The fish is fresh, and they will tell you if a certain fish is not up to snuff on that day. They are really accomodating about making the sushi (cut, amount of rice, etc.) they way you like it.
I go here as often as possible and recommend it highly, as finding a really GOOD sushi place is hard.
My only complaint is that the sake selection is very limited. That's a small complaint, as it is the fresh and ample fish that I'm after.
Pros: fresh fish, great service, clean
Cons: few sake selections, closed on Sundays
