The number of food trucks on the streets of Phoenix these days means that it's pretty easy to find one when you want. The size of the gatherings can range from a single vehicle to dozens, like at the annual Street Eats festival. But our favorite place to be handed food through a side window is Food Truck Fridays, put on by Rad Food Trucks. Each week from 11 a.m. to 1 p.m., a rotating assortment of trucks lines up in front of the Arizona Department of Corrections at 16th Avenue and Jefferson Street (insert prison-food joke here). There are about five to seven trucks each week, and choices often include Adam Allison's Left Coast Burrito Co., perennial favorite Q Up! Barbeque, Korean fusion eatery Hibachibot, and build-your-own-bowl joint The Wandering Donkey. If you're not within walking distance, there's plenty of free parking near the State Capitol, and there are a number of picnic tables for lunching al fresco. Check out Rad Food Trucks on their Instagram, @radfoodtrucks, for the weekly schedule.
