I've been itching to try the Mexican hot dog vendor who sets up shop at night near (20th St.?) and Indian School. I've also noticed a mobile taco vendor in a lot at night in the 30-something block of E. McDowell. That got me wondering... are there other mobile vendors worth seeking out? In L.A., for example, Venice beach residents know that a certain "coach" has some great ceviche tostadas and burritos. Meanwhile downtown office workers hit up cheap but good RVs serving everything from tacos to gourmet wraps and salads. New York has great restaurants but also great street food vendors. Maybe it's the heat, but I don't see much of that here in the PHX area. On the flip side, we're a mobile town which likes wallet-friendly finds, so it would also seem we'd have more vendors setting up shop in certain parking lots that are empty after hours - especially in the non-summer months. Maybe the local laws make it tough to do?
