3. El Chilango
Tacos aren’t just for Tuesdays, thanks to El Chilango. This Rosslyn truck, which you’ll find parked at the corner of 14th and Quinn Streets in Rosslyn, is open from 11 a.m.- 8 p.m. most days (closed Sundays). With various meats to choose from, you’ll get the authentic Mexican experience, complete with two corn tortillas per taco (tip: divide the meat evenly between the two tortillas), plus lime and cilantro. Even better, it’s a great deal at at just $2.50 a taco. This truck is a cash-only vendor, so you may need to hit the ATM first.
