Two fishy taco options were found on the à la carte portion of the menu. The fish taco ($2.25 each but for some reason you have to order two) is a sauteed tilapia fillet marinated with pico de gallo and a guajillo sauce. The shrimp taco ($2.75 each) is sauteed shrimp marinated with the same fixings as above. Both are served in housemade corn tortillas and topped with a healthy dose of cilantro. The fish was properly seasoned, but the flavor was not enough to carry the dish, which involved little to no other ingredients. The taco was, however, improved by the addition of the tomatillo salsa (one of two that accompanies the free basket of chips). The shrimp taco proved to be a much tastier choice. It was cooked perfectly, opaque yet tender, and carried quite a spicy and flavorful kick. So I'd suggest sticking to those. And ordering them in any quantity desired, odd or even.
