This is one of those places that looks like it could be a classic hidden gem. El Chalan is located at 1924 I St, NW:
El Chalan Restaurant was founded in 1975 by Pedro and Elsa Espinoza. After, a few years in the DC metropolitan area they opened a carry-out in Arlington, Virginia. They initially sold traditional American food such as hot dogs, hamburgers, and fries during the week and Peruvian food was served only on the weekends. Soon, there was increasing demand for the Peruvian menu, and they converted the carry-out to a restaurant and changed the name from Washington Lee Carry-out to El Chalan Restaurant.
El Chalan was the first Peruvian restaurant in the DC metropolitan area, and continues to be one of the most recognized in the area, and has received multiple favorable reviews. Located on 1924 I Street, El Chalan serves up delicious Peruvian fare every day of the week. Our most known dishes are the lomo saltado, causa, and ceviche. The pisco sours are also very popular.
