"Bar La Opera is one of the most storied bars in Mexico City history (revolutionary hero Pancho Villa famously fired his gun at the ceiling in 1910). Come here for straight tequila flanked with sangrita, a salty-sweet traditional tequila shooter. Sip a little tequila, follow it with some sangrita, then suck on a lime wedge and repeat. It's not a cocktail place, but the bartender will happily make rum and Cokes or tequila sodas." - Scarlett Lindeman
