Best burgers in town

Really, really good burgers. Local beef, lots of different options. Most people I've talked to love the fries, but I personally find them to be a little soggy. It can also get a bit crowded, if you go at peak dinner time, you will probably have to wait or fight someone for a seat. My recommendation... read more

Dropping our son off for his first year at NAU gave us a chance to explore a new town. A friend recommended this place. I had serious doubts when the line had about 20 people outside the door. But the line kept moving and the food was great. I havent had a burger on an english muffin before, but it... More

Obviously this is a popular place to enjoy a burger, we decided to jump and try 1xMARY@12USD + 1xWRIG@13,75USD + 2 local beer, total 52USD. Rosemary French fries were nice so were the burger but this is after all only a sandwich so nothing special for 52USD. I was amused by the billing system (you have to sign on a... More

I love their burgers and I'm usually a vegetarian. The beef is all fresh and delicious. All of the cows spent a happy life outside Prescott, AZ (a few miles down the road) and haven't been injected with hormones or antibiotics so I feel safe ordering my burger medium rare. Lots of fun combos and for $10, you will leave... More

If you are in Flagstaff and passing through, this is an absolute must stop! We are die hard fans of Diablo. The burgers are amazing and fries are soo good!! The place is small and not much seating, but we think the burgers make up for it! They are a little pricey, but overall worth it. Eat Here!

I've been there twice and dream about the burgers. Vitamin B was designed for me with Beets, Blue Cheese and Bacon! I wish for the day the open one in the Phoenix area, but until then, I shall go on trips to Flagstaff. Highly recommended.

I had read so many great reviews, but was disappointed. First off, it is difficult to locate the entrance - almost walked into the establishment next door. Have to wait in line to place order with the one person working the counter. Very little indoor seating, so sat outside, which was fine as it was a nice day. Have their... More

Good burger and tasty fries. Nice outdoor seating. Yes, it is a little pricey but not outrageous. At 8:30 on a Wednesday night there was a lot of energy in the area.

An acquaintance recommended Diablo Burger as being the best in the downtown area of Flagstaff. He said, expensive but uses fresh ingredients . While the aforementioned is probably true it does not justify a price of $11 for a plain burger that comes with fries(they call them Belgian and they are delicious) but the burger, which they serve on an...

I've had a lot of veggie burgers in my time... Some good and some epic fails. Diablo's locally grown burger is super scrumptious!! I had mine with blue cheese and grilled onions. Love the house wine and the community seating. I'll be back next time I'm in town!
