I used to eat at the Wahoo's in Orange County & L.A all the time. When I moved to Corona, this was one of the things I missed and was hoping they'd open one in my area.
The food is unique and delicious. Its sort of a Mexican/South American/fusion type cuisine. My favorite is the fish bowl with the Green Sauce (roasted pepper cilantro dressing). If you don't like fish, their chicken and steak are equally good.
The decor is really neat too - lots of surfing posters and surfboards - you'll feel like you're right by the beach.
Prices are very reasonable. This place is definitely worth the trip!
