I hadn't heard of this but apparently today is food truck Friday in
TGP.
4pm-8pm
"That’s right, the finest food trucks on St. Louis’ streets, including
Pi On the Spot, Cha Cha Chow, Fats Pierre, Mangia Mobile, The Sweet
Divine, Sarah’s Cakestop, Holy Crêpe, Falafelwich Wagon and more will
be there, excited to meet the friendly faces of their hungry
customers. So whether you’re a regular at the windows of these
creative culinarians or are simply wondering what this whole food
truck trend is all about, grab a blanket and a chair and head on down
to Tower Grove Park for a night of great food, good times and the
friendliest darn truck drivers you’ll ever meet!"
