Known for one-of-a-kind Mexican fare served in a dining room as authentic as the food, Casa San Marcos is a Tulsa favorite. If you don't feel as if you've been transported to Mexico with a bite of a carne al pastor taco, you will when you see televisions turned to Spanish-speaking channels and hear the speakers channeling Mexican music. Enjoy traditional dishes like tacos stuffed with carne asada or a variety of mariscos. Casa San Marcos serves a horchata that is highly recommended. This refreshing drink is made with sweetened rice milk and is made fresh at this authentic eatery.
