Ever since Daily Candy wrote about the Hallava falafel truck last week, I’ve been craving the stuff. Trouble is, I can’t seem to find it. Per Hallava’s MySpace page, they supposedly operate at lunchtime Tuesday through Friday at 3667 1st Avenue South, but two trips last week and one today left me wanting. I called Jonathan, thinking he’d know, and he told me that he’d tried in vain to visit the Capitol Hill stop he’d heard about.Where in the world is Hallava falafel?And is it worth going?
