Tres Rios is the best new restaurant in Pittsburgh! Cool atmosphere, impeccable service and amazing food and drinks! I really loved how the guacamole appetizer was separated into two even (and large) portions so I didn't have to fight over the last scoop with my boyfriend they also have great drink specials! The rosemary margarita was delish- the perfect amount of sweet and salty, with a little bit of spice. Tres Rios will definitely become a regular spot for me! #3RMardiGras
