I've been to Takara a handful of times now and as someone who lives in easy driving distance of it I am sad to say I didn't go there for years because of the lackluster quality of its State Street branch. Don't make the same mistake I did, the sushi here is very good!
I've had their steak hibachi and unlike many I've had elsewhere they did not cook the steak into a dried out mess but left it still somewhat tender. The rice was good and overall the meat / rice / vegetable ratio is pretty close to optimal.
As far as their sushi I've had a variety of rolls and found them all to be very good. As I tend to favor simpler rolls rather than their more elaborate fair that's about all I can say for them but others I've gone with have gotten the fancy ones and at the very least they are beautifully crafted (since I did not steal their food -- that's what I've got).
Their ambiance feels very Japanese which is something lacking even in some of the better sushi restaurants in Madison.
On State Street, hit up Wasabi, but if you are on the near west side and need a sushi fix -- you ought to go to Takara.
