desperately seeking sushi

So I've been craving sushi lately. I don't think it's a pregnancy thing--more of a "98-degree summer in Colorado where cool, light meals are perfect" thing. We've got good sushi restaurants in the Boulder-Denver area--even one right here in little Lafayette--but of course they present a dilemma: I'm not allowed to eat raw fish. So far, I've been satisfying my craving with the occasional California roll or unagi (the eel that tastes barbecued). Do any of you with more sushi expertise than me have suggestions of other cooked fish sushi rolls I can indulge in? (I had a vegetarian one the other day, which disappointed me because there were too many crunchy bits.)
