Phil Villarreal from The Consumerist recently discovered an emerging trend at a San Francisco McDonald’s. Apparently a cult following is growing and ordering off of a McD’s secret menu. One item off that menu is the Mc10:35. It can only be ordered during the changeover from breakfast to the standard menu hence the 10:35. The Mc10:35 is the “unholy but oh-so-hot union” between the McDouble and Egg McMuffin.
