Finding a taco that compares to options in the West and Southwest is a tall order on the opposite coast. Luckily, Washingtonians have La Tejana, the Mount Pleasant tacqueria serving up the best breakfast tacos in the city. Co-founded by Ana-Maria Jaramillo, who is a native of the Rio Grande Valley in Texas, and Gus May, a D.C. native, La Tejana is that fix—the long lines that gather every weekend morning to secure one (or three) in rain or shine are proof. Try the Tio Willie, which comes with cheesy scrambled eggs, queso drizzle, bacon, and friend potatoes. Another popular option is the 512, which adds Texas-style BBQ brisket to the breakfast taco party.
Even if you did make it into the morning taco line, La Tejana makes for a great night out thanks to its lively cocktail bar (note the reservation link above is for the bar only, and the taco shop doesn't take resevrations). Evening food offerings include soft and chewy churros with dipping sauce, and queso dip you'll want to swim in.
