In Flagstaff to for the weekend and was surprised to hear that Diablo Burger was in town. I've seen that the Tucson location was voted as having the best burger in AZ. Tonight I had the Blutarsky and don't regret it. Had the 928 farmhouse ale to go with it. Restaurant is very small but worth the visit.

The burgers are to die for! But the service is persnickety and the seating arrangements are some of the worse I've ever seen. Not worth the inconvenience.

Read review this was the place to eat in Flagstaff, hard to find but thought​ ok must be one of those great finds right? Very disappointed. There are only 4 tables inside and it was cold and windy outside. We weren't allowed to sit at a table until after we ordered our food ( first come first seated and served).... More

This place is really small and looks like it has outgrown itself and unfortunately that is spoiling the experience. For sure the burgers are great and the service is also good but people need somewhere to sit - you can't seriously ask people to eat their meal outside in Flagstaff (it was freezing!!!!). Seating inside uncomfortable and cramped. Hope they... More

Ate there with my family while staying in Flagstaff over spring break. My son very much enjoyed his burger while I'd say in my case I wish I had ordered my usual medium well (they recommend medium-rare). I bridged the difference with medium, but I'd go for medium well next time, it was a bit "mooey". The fries were OK,... More

We almost turned around to find another spot when we saw the long line to get in, but there's a process that works. You stand in line to order, and by the time you order, a table frees up. The burgers were some of the best we've ever had. Definitely worth the wait!

Limited menu, only burgers. Great staff. Difficult to find parking. Burgers are pricey but outstanding.

Not a whole lot to say about organic burger place not very good taste kind of on the bland side the bun I don't even know how to explain the bun it taste like Sawdust, but maybe some people like that so I think you'll just have to try for yourself disservice there's no waiter or waitress you have to...

Little place near urban park, six tables capable of holding 6 each, plus outside. My delicious burger had cucumber chips. Love that. Coke sold from bottles. Really good.

Absolutely the best burger in Flagstaff AZ. You have to go to Diablo Burger and try the grass fed beef medium rare is burger perfection.
