I love Food Truck Friday! It's such a great event for a chill Friday night outside of Uptown. It's very nice to be able to sample from several food trucks at once but the food trucks only offer regular dinner portions so technically you might only be able to sample 2 food trucks each Friday before you become so full that you won't want to walk back to your car. I suggest hitting up one truck for your entree and side then picking a different food truck for your dessert. :)
If I were to give any advice for a first-timer out at FTF, it would be to definitely get there early. If you show up at 5pm, you could be one of the first people in line at the food truck of your choice BUT if you show up any later than 5:45, you could be waiting in line for 30 minutes easily. The last FTF I went to, I saw a friend wait in line for an hour for a Papi Queso grilled cheese. Yeah... you would never catch me doing that.
Parking is usually a nightmare since there is virtually none at the site so you will have to park somewhere nearby and walk over. You can park in the parking garage in the condo building across Camden for free. I actually park at All American Pub and walk over from there. Oh, and bring your own chairs unless you want to sit on the ground or stand while eating. There are nowhere near enough tables out there for everyone to sit. Also, all of the food trucks take credit/debit cards so you won't have to bring cash if you don't typically have it. Bonus there.
I do love that the food truck scene in Charlotte is growing and I love to support new and local businesses. I highly recommend bringing a few friends out to FTF to try what the Charlotte food trucks have to offer!
