(COOKING CLASS) Hawaiian waters produce a lot of strange-sounding but totally delicious fish, which is why this cooking class, with Flying Fish chef Christine Keff, should be so cool. Keff knows everything there is to know about seafood, and she'll lead participants in a tasting of a dozen or so ocean-going oddities-like ono and moonfish-side by side. The fee covers lunch and wine. (Flying Fish, 2234 First Ave, 728-8595. 10:30 am, $55.)
