There are plenty of choices when it comes to late-night Mexican food around the Valley; an endless parade of 'Bertos dots the landscape just waiting for midnight eaters. But if you want something a little tastier, we recommend a visit to La Frontera #1, a permanently stationed food truck in Central Phoenix. The menu is full of simple, traditional Mexican fare. Make sure you grab napkins with your al pastor burrito; the meat's savory oils tend to drip down your arm. Tostadas are piled high with toppings, and the vampiros come heavily laden with meat — don't overestimate how many you'll need or you'll have a ton of food left over. The truck is open until 1:45 a.m. Wednesday through Saturday, and until 12:45 a.m. the rest of the week. La Frontera #3, a food truck in the same parking lot with a focus on seafood shares the same hours, and the same payment policy: Purchases are cash-only.
