Terrific teriyaki in Seattle?

[cynbad]

A friend's in search of suggestions that would be good for a teenager who loves teriyaki (and not a whole lot else....) for a birthday outing on Sunday. Teriyaki's been off my radar for a number of years, though certainly there are--seemingly--hundreds of neighborhood spots in Seattle. Any stand out as particularly good, and apt for a birthday dinner?

My personal favorites are Nasai, they have a bunch of locations, including two in the U District, though none are particularly nice...the front of the one on the ave has a decent seating area though...
