I went to the Taco Mesa in Costa Mesa the other week and had the special which was a blackened yellowtail on a bed of mashed chayote (I think that's what it was...it was orange, kind of a cross between squash and a yam) with grilled carrots & asparagus and a butter sauce with a tropical fruit salsa on top. It was PHENOMENAL...beautifully presented, and $8!!! I also tried the roasted tomato soup which was sooo tasty. Like a pureed tortilla soup. This has to be one of my favorite places to eat...when they brought the plate of yellowtail out to me, looked like it had been prepared by a 4 star restaurant (except that it came on a paper plate). The sauce was exquisite, the fish was so fresh and perfectly cooked, and even my boyfriend who hates seafood tried it and liked it.
