Looking for a great burger in Flagstaff? Diablo Burger is a great stop. Amazing beef patty burgers, surprisingly tasty english muffin buns (ya, but hear me out), truly fresh toppings and stellar fries. I've been spending the long weekend in Flagstaff trying out local haunts for food ideas. Diablo Burgers was a gamble for us cause we hadn't heard of it, and only went cause it was close to our nearby hotel. But that gamble paid off.Located right downtown Flagstaff in the restored square in the historic downtown area, the burger stop has a large outdoor table and hightop seating area. Inside are a half dozen hightop tables if you want to drink alcohol or be indoors. The whole decor and vibe is rustic but renewal vibe, very fun.The menu is basically about a dozen selections of different burgers, all featuring local high grade 95% lean beef (really, it is truly worth the taste), your choice of condiments (via the burger name) and the unique english muffin bun. The english muffin bun is absolutely a brilliant and fun thing. And it totally works. Less carbs, and really great container that doesnt get soggy holding their massive patties.The fries aee likewise excellent, thin sliced and crispy natural cut fries. Love it.Prices are a out 15 per burger and that includes fries.The staff is courteous, helpful and patient even with older people asking lots of obvious questions :) .If you are in Flagstaff, or visiting, this is the absolute best burger stop in Flagstaff. Try it!

So happy this location is still open after the Tucson location closed.Pro tip, google takes you to the wrong spot, it’s in the back of heritage square and you can’t drive to the door.Easy to spot when you see it, and the inside has Lipitor’s seating.Staff is friendly and the burgers are amazing.

I always love finding a nice surprise while traveling. The food is excellently crafted here. My husband is a burger aficionado and declares this to be in the top five burgers he's ever gotten. He got the Big Daddy Kane and I got the grilled cheese with fried egg. Both were very flavorful. The fries come seasoned with rosemary and were some of the best fries I've ever tasted.

Super fantastic food and a wonderful staff! The fries are to die for and the burgers are delicious!!!!

Our party of six went here on previous review recommendations. Limited seating indoors, lots of outdoor seating-nothing fancy. Order your selection from a posted menu. They recommend medium rare, but respect your choice. Staff brought our orders out to us, very helpful. Burgers were enjoyed-nothing really special.

An out of this world burger experience. I’ve had 100s or burger in my short 2+ decades of living and I can tell you that this burger spot has stolen my heart when it comes to juicy meats. 10/10 would recommend to a friend.

We heard this was the place for runners to go and my budding collegiate runner needed to visit. Great vibe and better staff—we loved being there and being part of the experience.

We tried Diablo Burger after reading all of the reviews and I have to say, it lived up to the hype. I expected this place to be a sit down joint given the price point, but it was more of a fast casual arrangement which was nice too. It was unseasonably cold during our visit (snowing in late March), but the heated patio area was spectacular! My husband and I both had the Merylin and loved our meals. The food wasn’t greasy at all. The fries were delicious and perfectly seasoned. I would stop by here again. My only caution is that it’s on the higher range of fast causal price point wise. Otherwise, I wouldn’t hesitate to recommend this place.

Our family stopped on our way out of Flagstaff, a meal for the road. Two different burgers - a mushroom with swiss and a cheeseburger - and both were excellent. Toddler had a toasted cheese which we all enjoyed :) (She just wanted the delicious fries.) Two of us had the beet/blue cheese salad which as fresh with a nice amount of cheese and beets and tomatoes on organic greens. The service was prompt, friendly, and helpful (seat for toddler). Lots of different burgers on the menu!
