the two most terrifying words in the english language are "seafood buffet."
the only tolerable one i'm aware of is the todai in honolulu, where things seemed fresh. too often, the squid is soapy, the fish has freezer burn, and don't even get me started on the fake "mini" lobsters.
buffet seafood is cheap, in exactly the same sense that "50% yesterday's catch" at the seafood market is cheap.
