Casa Rio

"Watching the river flow by with a margarita in hand is one of the best ways to while away an afternoon in San Antonio, and at Casa Rio, you can do just that. The restaurant’s colorful umbrellas have lined the River Walk since 1946, providing a postcard-perfect backdrop for sampling enchiladas, flautas, fajitas, and, of course, icy-cold margaritas. The oldest restaurant on the riverfront, Casa Rio is beloved for its authentic Tex-Mex cuisine, but its real charm lies in its ambience. Request an outdoor table and let your worries float away with the river. Just be sure to decide between frozen and on the rocks first."
