The third time was the charm for Mohamed Jamal, who cycled through several business ventures before settling on the perfect one. He first opened a candy store on 17th Street in 1989, which he then transformed into a juice bar, before finally arriving at the space’s current iteration: Rainbow Falafel. Mohamed used the recipes he learned at his grandmother’s knee during his childhood in Syria to create a healthy, Middle Eastern menu. “We stick to all of the old-fashioned, classic foods and never change them, ” Mohamed affirmed, adding that the freshness and preservative-free nature of everything he serves is key to his philosophy. Offerings include the eponymous falafels served in veggie-filled sandwiches and platters, as well as stuffed vine leaves, spanakopita, hummus and other spreads. Impressively, most of the spices and special ingredients are imported, such as tahini from Lebanon, olives from Greece and mango juice from Egypt. To Mohamed, who runs Rainbow Falafel alongside his wife and son, the restaurant’s prosperity is easy to explain — “We are always here and we are always happy. ”
