ACR Elotes is certainly the best elote cart in metro Phoenix, but it's also one of the most elusive. It's worth chasing down this particular elote cart, though, which does not always keep regular hours but which makes regular appearances on Calle 16. Bring cash (no cards accepted, at press time), and prepare to delight in the pleasure of a cup of freshly prepared elote. The kernels are tossed in bright, vivid blend of cotija cheese, mayo, butter, lemon juice, and secret spices. True, there's nothing particularly revelatory about it, but it's somehow still a cup of corn for the ages.
