EAT AT THE SUSHI BAR.
The table service is ok, but you miss out on this place's best feature if you're not at the bar. (unless you're part of a large group, I guess...even then, I'd try to just take over the bar, if you can do so without being rude?)
I think I tried most of the rolls they offer, plus several custom offerings by the chefs...never once did I not slow down to savor what was going on in my mouth. If Osaka is where I fell in love with sushi, then this place is where it became a torrid affair.
Order as much as you think you can eat, and make sure to share your sake or beer with the sushi chef...nothing is more fun than a liquored up sushi chef! Plus, once they start pushing their custom creations on you, then you know you're knocking on the door to excellence.
(favorite chef from a couple of years back...Yeung. If he's still there, find him, buy him a shot, and get the night started!)
