Mariscos / Costa Azul is actually two restaurants under one roof. Collectively, the have a wide variety of economically-priced food. The service is fairly quick, so it's a great place to stop if you're in a rush.
Not much to look at in terms of decor but the food more than makes up for it. Great place to stop if you're in a rush and need something tasty.
The two taco combo with verde is fire!
