Opened in 1946, Casa Rio is the oldest restaurant on the River Walk and was modeled after the very first true Tex-Mex restaurant in the entire country which opened in 1899 and went out of business in 1960. We now carry on the tradition of serving the “Regular Plate” which consists of a cheese enchilada, Mexican rice, refried beans, a tamale, and our famous Chili con Carne. This was created as a sampler plate so our visitors could try a little bit of everything. The chili is unique to our community because it is based on a recipe used by the “Chili Queens” in the late 1800s. The Chili Queens would serve visiting military and cowboys their famous chunk meat chili doused in all sorts of spices in the nearby Alamo Plaza. Next time you visit the San Antonio River Walk, don’t miss out on this staple dining experience, underneath the famous umbrellas!
