Wow. Maybe I don't have to go back to Japan to get really good seafood. According to this article in the Japan Times, some of the most expensive delicacies sold at Tsukiji Jogai Shijo are from the Gulf of Mexico. I could probably pick up some good yellowfin tuna at Central Market.
"Among the more exotic delicacies from overseas are yellowfin and bluefin tuna from the Gulf of Mexico, shrimp from Indonesia, sea bass and sea bream from Chile, salmon from Alaska, lobster from New England ..."
