Food trucks get a bad rap sometimes, but they often have the most authentic cuisine a city has to offer. That definitely holds true when it comes to tacos in Arizona, and these nine trucks are absolute hidden gems. Hope your taste buds are ready for a flavor explosion!

1. La Frontera 1 (Phoenix)

This late-night food truck might be unassuming, but its food certainly isn't. Several different meats are offered, including carnitas, chicken, steak, and barbacoa, but one thing remains the same across the board: deliciousness.

3. Taqueria La Hacienda (Phoenix)

This popular walk-up taco joint is complete with a large covered patio to enjoy them on. Although the line is always long, it's well worth the wait - after all, where else in Phoenix can you find $1 tacos that actually taste good? Many patrons claim the carne asada is Phoenix's best, hands-down.
