Welcome to Rio Rio Cantina, where California Tex-Mex is the specialty – the best of all that "Mexican" food has to offer. Rio Rio is a colorful fiesta of freshness and that South-of-the-Border flavor, in portions so generous guests often gasp when their order arrives. Spacious patios and riverside dining areas offer outstanding views of the famed San Antonio River Walk. Rio Rio Cantina also features the popular Naked Iguana Lounge. Naked to the Bone, since 1986. Over 20 styles of signature margaritas, fine imported beers, and a prime perch to watch the river traffic go by.
