Indulge, it’s a holiday (sort of). To launch its anniversary month, Latin-inspired restaurant Tango on Capitol Hill will offer its diners free El Diablo desserts today. Tango’s most popular dessert, the El Diablo is a hunk of dark chocolate topped with tequila-caramel sauce, cayenne pepper, and almonds. It’s April Fool’s Day! That counts as a holiday, right? That means that calories don’t count, right?Right?!
