Diablo Burger, Flagstaff AZ

First time here. We shared the Big Daddy Kane. Very good burger. One of the best I have had. Served on English muffin a plus.

The whole menu is a bit pricey, but the Señor burger is on point! Friendly staff, good atmosphere. Definitely worth it.

Such a great place! It is not big but the flavor of the food is! All locally sourced ingredients make this place a MUST to eat at! Try the Wrigley Field. SOOOOO good!

Great service, great food! Wish there was more space to eat, more table space, but service and good made up for it.

Visiting for the weekend. First time eating here, and it was pretty good. The staff was amazing, super helpful, extremely nice. Nice atmosphere.

Experience was iffy at best. The staff was extremely rude and unhelpful in the worst of ways. We went with said staff's "recommendation" of a medium rare burger. The burgers that were served were RAW in the middle. Literally COLD and MOO-ING. I've eaten enough meat to know what medium rare is, as it is my preferred choice. An overall disappointing experience, not worth the time it takes to find a parking spot nor is it worth the price.

I really like that the recommended doneness is medium-rare, and my burger was cooked perfectly. I did not like the English muffin bun, however. This is apparently their thing, and there isn't any other choice. There's nothing like a soft, pillowy bun with a burger. I found the muffin too crisp and chewy, but of course that's just my opinion. The fries were excellent, and the coffee BBQ sauce was awesome with the fries. The draft beer selection was minimal (3 choices) but they did have a few ciders and two wines. Overall pretty good.

Best. Burger. You will EVER have. They are always delicious but always busy. Fried are delicious, beer is good, and for God's sake, get a burger here if you're in town. All locally sourced, and it makes a difference. Very kind and friendly staff.

Burger was great. The only thing I can say that was negative is the prices to order is very slow. It seems like it took 5-10 minutes out order.

Great burgers, but super bad service and small seating. I was waiting for my wife to order and found a table outside that We could share with another family but moments later I was very rudely told to get up by a waitress because I cannot sit without having my food ordered yet. I tried to explain to her that my wife was ordering the food as we spoke but she would not listen.
After my wife came over another waitress sat us down at the very same spot.

They have a gluten-free option. It was THE best. Place has a super long line very limited seating but it's one of those places that's like that but is worth the wait was delicious!

This burger joint is really, really good. Tons of unique fresh veggie options, small and cozy inside, huge patio, and decor that is all Flagstaff. An English muffin is the default bun, and you can order a burger cooked Rare. Need I say more? Also got a salad. I had to ask if they grew the veggies right there, like in the store!? ! It'spatio faces a town square if sorts. Really cool and a place for families and kids. Enjoy!

The burgers are truly exceptional here. I've been twice and both times I was surprised at just how good they are. The ground beef is quality and prepared well. The buns are fresh and soft. Even the fries, which I don't normally eat, are actually quite addictive.

I give 4 stars only because the line really shouldn't take as long as it does. It took over 20 minutes for 3 parties ahead of me to order last time. If they can solve the line problem then this place will be golden.

It's been a few years since I have been here but this is absolutely my favorite burger spot on the planet. It's delicious and I always stop in when I'm in town.

This is a fast food joint but with the quality of a first class burger restaurant. Highly recommended.

Great food! Burgers and fries are excellent. Only complaint is there is ALWAYS a wait. Usually 30 minutes to order and another 15 minutes for the food to be delivered.

Best burger we've had in while. Outdoor seating was great. Great service all around and in a good location for people watching and walking around.

I want to give Diablo burger a higher rating. They are friendly (and dog friendly on the communal seating patio). The fries were great. The menu is eclectic and well thought out. The problem is that out of my party of 3 who all asked for medium rare (it even says thats how they want to cook) all 3 were not just over rare but well done.

The burgers are impressively made: great taste, fair builds - though the construction lends itself toward 'imminent collapse' the balance of flavors is worth managing the eating balance.

An acceptable beer selection, and the quality of everything our family of four ate was excellent.

The staff were friendly, paying attention, and truly engaged.

The atmosphere - we had a bonus: there was a beautiful thunderstorm shaking the area that evening, so the outside seating was magnificent and spectacular.

If you love burgers and you're near here, make the trip.

This little burger might be small vut it's all you need!
One of the best burgers i hade in Arizona!
If you traveling in flagstaff area you probably want to finish you'r day there!
Thanks DB

Best burgers in town. A local treasure. Worth the wait that is usually the norm. The shared seating adds to the friendly vibe of the place.
