"This always-packed Capitol Hill bar has been a boozy slushy destination for years, with various rotating flavors. But it really hits the mark with the creamy avocado margarita, which seems especially engineered to deliver an invigorating brain freeze. New taco window El Xolo is in the house now, serving up slow-roasted pork in tortillas nixtamalized from scratch and airy light queso-topped chips." - Gabe Guarente
