Was in Costco on 75 yestereday and was perusing the fish case and noticed that they had Langoustine tails (prev. frozed) for $11/lb so i thought what the heck. Not bad and something differnt. I don't know about the provenace of them, but they were pretty good and something different. I cooked with past as they were smallish. Just thought I'd throw it out there in case anyone was interested.
