Gnaget,
I tend to agree with you. There's a lot of technique but not that much creativity or variety. (Probably get some dissent on this).

Also I don't really think of going for sushi the same way I think of going to a really fine restaurant. It's more like the local joint where you hang out. Find a place you like not too far away and just keep going back....not much need or interest in trying out anything new. You know them, they know you, fish is good, beer is cold. Once you get to a certain point, the flavor has a lot more to do with Neptune than with the chef.
