Could street vendors already be jumping the shark? The folks at Fox Searchlight are pushing them in that direction. They’re doing a big promotional thing this weekend where they hitch up with street food vendors across the country and give away food to the first 500 people who show up. Their San Francisco partners: The Tonayense truck and the Creme Brulee man. That’s right, the very model of the new underground street vendor scene is getting on board with Fox. Comparisons to those graffiti ad campaigns of a few years ago spring to mind, but we can’t complain too loudly. After all, it is free, good food. If you want to get yours, head to the Tonayense truck at 22nd and Harrison streets at 2 p.m. this Sunday. Creme Brulee guy will also be doing his at 2 p.m., but that location isn’t announced yet. You’ll have to follow him on Twitter, because that’s how he rolls.
