The food is psuedo-Mexican, with tacos, burritos, taquitos, and quesadillas. They also serve salads, soup, and a "Wahoo's Sandwich." My favorates is the vegetarian taco and the vegetarian burrito. The taco shell is soft--- steamed, not fried. The veggie filling for both the taco and the burrito is rice, black ahi beans, lettuce, salsa, and cheese. (If you do not eat cheese, ask and they'll leave it out--- no problem.) One may also get sour cream and / or guacamole with these items if one wishes.
If one is not vegetarian, one may choose from beef, chicken, or fish fillings for the tacos or burritos.
Beer, wine, and soft drinks are available.
The cost of the food is rather high, considering most of it is rice and beans. One veggie taco costs $3.25, which seems rather excessive to me, but I figure it is worth it to me to have someone else do the cooking and the cleaning up.
The "atmosphere" is mostly Surfer-Dude / Skateboarder, and it seems strained at some locations in-land: trying too hard to be trendy, with-it, and cool. Still, it's a fun place to go. Even the local Highway Patrol where I live goes there (better for them than doughnuts).
On the Shy David scale of from one star to six, I think Wahoo's earns three stars. Though the manager I talked to denies if, I've noticed that one receives less food if one orders "take-out" instead of eatting on the premises.
