The sibling of Georgetown’s excellent Fonda La Catrina, El Sirenito is a cocktail lounge pouring 50 tequilas and more than 20 types of mezcal. The menu of light fare is short but filled with plenty of seafood: ceviche, tacos de pescado, coctel de camaron, as well as small plates of clams with chorizo and grilled octopus with guajillo chile. It’s the perfect place to grab a drink as you wait for a table at La Catrina, but you may end up lingering for a while, especially if you find yourself on Sirenito's lovely back patio, which seems to transport you out of the industrial neighborhood. Have another cocktail, sit back, and watch the airplanes buzz overhead.
