Diablo Burger

Diablo Burger

Diablo Burger is a Flagstaff institution built on a simple idea done right: local, open-range Arizona beef served on branded English-muffin buns. It is counter-service casual, tucked into the downtown Heritage Square area, and it has earned a devoted local following over the years.

The burgers are the headline, but regulars will tell you the herb fries are just as much a reason to come. Portions are honest and the sourcing is a point of pride — this is a place that genuinely cares where its food comes from.

It makes a great, unfussy lunch stop between wandering downtown and heading out to the trails. Expect a line at peak times; it moves, and it is worth the wait. An easy, satisfying stop on any Flagstaff day.
