Picture This: A beautiful sunny day. The smell of fresh street tacos drifting into the air. The sound of your friends sighing after a cold sip of beer. And a sea of food trucks tempting you to stop in as you wander upon rows of delectable food. What a nice dream. Though, of course, it doesn't have to be. You can make this a reality! This Saturday, the St. Paul Food Truck Festival will take over Lot D at the Union Depot. The event is free and full of 50+ food trucks, craft beer, and live music. The event runs from 11 am to 9 pm.
