Chef Alfredo Solis and sister Jessica evoke the flavors of their native Mexico City at their pair of taquerias—don’t miss “basket tacos,” soaked in guajillo salsa and stuffed with black beans, chorizo, and chicharrones. We prefer shoe-box-size El Sol in Logan Circle for lunchtime (a dazzling array of tacos, huge torta sandwiches) or lingering peacefully over chicken cloaked in inky mole. The newer, bigger Mezcalero is our pick for a lively scene come evening, thanks to a bar serving more than 60 varieties of mezcal, jumbo margaritas, and stomach-padding fare such as queso fundido and stuffed gorditas. Also good: Hawaiiana torta with cheese, pineapple, and ham; chiles rellenos.
