Casa Rio – Mexican
Stepping into this vibrant riverside landmark, guests are greeted by the rhythmic crunch of warm tortilla chips and the festive hum of a bustling dining room. Tables overflow with bowls of velvety gold queso and zesty shrimp ceviche, while the smoky aroma of slow-simmered chili con carne mingles with the sweetness of charred Market Street corn. It is a place where every bite of a toasted quesadilla or hand-mashed guacamole feels like a celebration of bold, sun-drenched flavors shared in a timeless, spirited atmosphere.
