Dude, have you ever had calamari any other way? LOL I guess it could be sushi, too though.
Anyway, to answer the question, it looks like calamari for the most part is pretty decent for you. I found a spot on the net with some nutrition info:
Calamari: serving size 3.5 oz., 92 calories, 1.38g fat, 233mg cholesterol, 15.58g protein
Watch out for the wasabi!
