The absolute BEST Mexican food in Phoenix! Every time I fly in, I make certain that my arrival time coincides with Popos OPEN for business hours and when my family picks me up, we head straight to POPOS on Indian School Rd from SKY HARBOR AIRPORT! The finest machaca beef I've ever eaten! I dream of it back here in Ohio, my local Mexican restaurant doesn't know what machaca beef is...Oy!! There's sometimes a bit of a wait (the sign of fabulous food) but the prices are moderate and the portions are generous! I can't wait to come back, AND I WILL BE BACK YUMMMM
