Undiscerning palate

Lunching at Sushi Train as I'm wont, I tried a new plate - plain rice bases topped with slices of mollusc identified on the menu as "hokki surf clam". The rubbery flesh was white with a bright orange-red edge and I'm guessing by the name came from either what I know as a pippi or something very similar. So how were they? To be honest, all I could taste was the wasabi underneath. Must be one of those acquired thingies :-)
