Head to Highway 307, just south of Av Constituyentes for a true local seafood treasure. El Oasis Mariscos looks very simple and local from the outside and once you step inside it offers a very laid back dining experience with excellent service. The shrimp and/or fish tacos are the best in town. Order them individually for about $.75 USD each. They serve them up on request in about a minute. Trust me, you won't stop at three. Muy bueno!
