My new quick fix in Cairo: falafel.
Just Falafel is a chain that provides clean, healthy options of the Middle Eastern veg simple street fare, the falafel. Inexpensive and with a huge selection of different cultural takes on the falafel (other than the original with pickles, there is a Greek, Mexican, Japanese option, to name a few).
The meal comes with the option of chips or french fries and a drink. Pictured above is a tasty and healthy hibiscus iced tea.
