When the successful restaurant group Grupo Plascencia bought Caesar’s Restaurante Bar (Av. Revolución at 5th, Tijuana), it certainly wasn’t predatory business opportunism. It was a bet on Tijuana’s future, on themselves and on a salad. This was in 2008, at the height of Tijuana’s dark period. A drug war raged and the traffic flow of gringos that was the lifeblood of places like Caesar’s had grinded to a halt.
