Diablo Burger

The overview

Arizona ranch beef downtown

Diablo Burger, on Flagstaff's Heritage Square since 2008, builds its burgers entirely from local ingredients: 100% grass-fed, open-range Arizona beef on branded English-muffin buns, with herb fries on the side. It sources meat, produce, and cheese from within a 250-mile radius as a matter of principle.

A small, fiercely local counter with a devoted following, Diablo turned the case for regional, sustainable sourcing into one of northern Arizona's favorite burgers.

A signal you can check.

This is a dated award record, published by The Centurion Awards after Diablo Burger cleared the 2025 evaluation for its market and category. It was not bought, voted on, or sponsored — the criteria are public, only winners are published, and an award that stops holding up is revoked, not quietly removed. Awards run one calendar year and renew only if the business clears the bar again. For everything else — hours, bookings, live reviews — go straight to the business itself.
