While not exactly a secret, this Little Havana speakeasy, situated above Taquerias el Mexicano restaurant, manages to make you feel like you've stumbled into a hidden adventure as you make your way up a narrow stairway and into a Mexican candy store full of hanging piñatas, sugar skulls, and assorted dulces coated in chili powder. Behind a false wall, you'll find a dimly lit room accented by velvet curtains, repurposed church doors, stained glass, and traditional décor inspired by Mexico's rich cultural heritage. Opened by Zack Bush, Ben Bush and Bill Fuller, the team that restored Calle Ocho's Ball & Chain restaurant, Los Altos boasts a killer cocktail menu heavy on mezcal and tequila. Pre-COVID, the space would easily transform into a sweaty dance floor on weekend nights. These days, it has been ingeniously rearranged into more of a cocktail-lounge setup, and guests can book a table on weekend nights. New lead bartender Ray Guzman has added new cocktails, like the "Canta Rico," a tequila-and-citrus blend inspired by a drink from Jalisco; and the "TLC" (Tamarind, Love and Chile), a mix of scotch, bourbon, tamarind, and habanero peppers.
