We have heard so many great things about these burgers and decided to give it a try while in Flagstaff. First of all, the line was just slightly out the door, its a small place, so it didn't look all that bad. It took 25 min before we even got to place our order, there is only one person taking...

This place was awesome! You stand in line and order your burger and give your name. Sit down then they bring your food to you. You will for sure have to wait for your food because it is always busy but it is worth the wait. I didn't think it would be kids friendly but for sure patio dog friendly.... More

Unfortunately I have not been able to enjoy the sunny terrace because they was a lot of people, but the meal was perfect and for a very fair price

The burgers were a little better than average. The place is very hip, but small and claustrophobic without the option of outdoor seating.

There are just a few tables and you sit with people you don't know. Being from Europe that doesn't bother me. Grab a beer as it will be awhile to get your food. The burger is really good. It is small and not worth the price to me. Burgers start at $11.I generally don't give negative feedback, but the table... More

As we were driving through Flagstaff we decided to stop and walk in the old town. We read the ratings of this Burger Bar and decided to stop for lunch. Burger is quite average , fries not that great , personnel nice but service average. 4 burgers and tap water $56 .

We found this place on Trip Advisor and lived the name. It was a Friday night with a lot going on in the square, but we got there right before they got super busy. The food was just spectacular!!! Rosemary on the fries was a bit weird, but ok. Not my favorite, but the burgers our group of 4 got... More

There's no doubt the burger is good but it's not worth the long wait Burger is small and thick so it's always undercooked

The ingredients are locally sourced and very fresh. Another big plus is that it is celiac-friendly. They have gluten-free buns and the fries are made in a dedicated fryer-- so they are safe to eat. It is very popular -- on a Friday night in July, the line to get in was about a 10 minute wait.
