I've been eating sushi for over 30 years, and view Kaiten-zushi, or conveyor-belt sushi, for what it is; the fast food of the sushi world. You always have pretty low expectations but sometimes it is better than you expect.
I've tried Kuru Kuru a few times and just haven't had anything good here. The vast majority of the rolls are based around shredded Surimi, or fake crab meat. This is fine for California rolls but I really don't care for the stuff, and in the case of Kuru Kuru even the Spider Roll is packed with a huge amount of this stuff. The roll selection in general is very minimal and boring. The nigiri-zushi is even less interesting with the occasional tuna or salmon strips going by. I haven't seen any sashimi, although it can probably be ordered.
Portions are small for conveyor-belt sushi; the roll pieces are quite small and few in quantity. I'm basing my opinion after eating at literally dozens of these types of places. Prices are high too, both for the quantity and quality. Maybe the owners took their clue from the Blue C Sushi chain, who also charges higher prices, but at least the quality of their product is better.
Service always seems kind of frantic, and nobody looks like they're enjoying their job, but at least everyone tries to do what they can. The layout of the place is a bit strange and it gets a bit cramped by the window when the servers are moving around.
I kind of view this as a "my first sushi" type of place. Looking around it seemed that most people had their wasabi mud mix going, where you could have dipped a McNugget into it and it would all taste the same. I won't go into the whole concept of when you typically dip sushi, but come on people, if all you taste is your soy and wasabi mix, what is the point?
No, Bellingham hasn't had any really great sushi since Moshi Moshi closed down. But Kuru Kuru is, in my opinion, at the very lowest end of what Bellingham has to offer for sushi restaurants. Go elsewhere.
P.S. - You can always drive 45 miles south to Belt Sushi & Roll in Smokey Point (Marysville). Good selection and they're very accommodating for special orders. And reasonably priced. If they opened a restaurant in Bellingham it would be the end of Kuru Kuru.
