Fodor's Expert Review District Taco

The line out the door at lunchtime is a dead giveaway that D.C.'ers have taken to this fast-casual, Yucatán-style Mexican restaurant that got its start as a food truck in 2009. While you can customize the toppings of your tacos or burritos, ordering them the Mexican way (with cilantro and onion) is a sure bet. Similarly, the breakfast tacos (served all day) never disappoint. And before grabbing your table, make sure you hit up the salsa bar.
