Got a menu in the mail from Ali Baba's Falafel, 7155 Wisconsin Ave., Bethesda, and immediately got a delivery. Their falafel is the best I've had this side of Max's, and they offer two sizes. The large is gigantic. They also offer a Kosher half smoked that is pretty tasty, and a small variety of other sandwiches including gyros.
Highly recommended, and THEY DELIVER.
