Other than the usual fast food joints that are open later in the evening, Chantilly restaurants shut down by 10 PM. Many of them close earlier. As other diners have pointed out, they have an extensive menu. In my experience, the Tex-Mex is just ok....Their Salvadorian food or their house specialty entrees are reliably good. If you're trying it out for the fist time, try their Plato Tipico which has a combo of Salvadorian delicacies. They do it right with plantains, crema, and a delicious tomato sauce for the pupusa and the tamale. Delicious. They're literally right next to the Dulles Expo Center, so if you're in Chantilly for business, chances are your hotel is very close. Recommend.More
