Actually, escolar is fantastic, it's a light, moist, mild white fish. I learned about it when I lived in LA and went to some of the premium seafood places, like Ocean Ave Seafood in Santa Monica.
IIRC, they told me it was an incidental type catch with some other more desirable fish, and it turned out to be really great on its own. Don't know if any of that is true, but I know it's my fav fish of all time....wish I could find some around here. Yummm
