Locals only! Almost!

4 tables inside, four outside. Ridiculously good burgers and fries. We had the smokey burger. Fantastic! Find this little hole in the wall (if you can)and you will find the best burger in flagstaff!

The burgers are meaty and dense, and the English muffin bun is a nice twist. Unless you're sharing or you have a big appetite, don't get too many toppings or you might not be able to finish. I think the cozy interior makes it feel more like a pub, very cute.

Been here a couple of times. Great customer service. I like the atmosphere. The grilled cheese was delightful. The hamburger smelled wonderful.

There is many burger toppings to choose from, friendly staff, local brews, and a cool image. Trust the staff, the medium rare default for a burger is good, gotta have a little blood when at diablos.

I went for lunch today, and I was pleasantly surprised. I have heard of Diablo a few times since in the area and I thought I would try it. In line I was a little overwhelmed by the small interior and the service seemed to be extremely slow, took about 15 minutes to order and I came at 3 pm,... More

Okay, I love the idea and the menu... for sure. But as a food-science type of guy, there's a few things I'd change: first I'd use a different recipe for English muffins... taste the ones at La Grande Orange in Phoenix and make something as close to this as possible. Second, I'd downgrade the meat... using high-end meat usually translates... More

The only vegetarian options are between a build your own veggie burger, or an $11 grilled cheese! I went with the veggie burger and picked toppings that surely would make anything taste good (blue cheese, avocado and grilled onions), but what I got was the worst taking veggie burger of my life. It tasted like spicy, flavorless cardboard and was... More

This was my first time at the original Diablo Burger in Flagstaff, although I have been to their location in Tucson, Arizona several times. They certainly did not let me (or my guests) down. Although we had to wait for a bit in line (I would guess about 15 minutes), it was well worth it. The restaurant there is pretty... More

We were told that if we wanted a burger that we had to go here. Aaron from the Hampton Inn told us that it was his favorite place and that it would be the best burger that we've ever had. And... HE WAS TELLING THE TRUTH. This little hole in the wall place is the best! Will recommend!

As a long-time Flagstaff resident, Diablo Burger is the most flavorful gourmet hamburger around. The owner has kept this restaurant small with beer & wine and 5 community tables indoors and a number of community tables outside. The pesto skinny fries are just as good as the hamburgers. The price is a little high, but you can't beat the local... More
