There's a singing falafel cart man who used to set up shop on the NE corner of 20th and Market. His cart was decked out in plants; he rarely gave you a choice of what you were eating (sandwich or platter) and it was the most garlicky delicious grilled chicken with apples, plums and pears.
I don't work in the area anymore but I haven't seen him since December. Anyone know where he's gone? If he'll be back? I miss him.
