Awful experience. They have the most inefficient line and service of any restaurant. People coming up to order, can't because there's a horde of people waiting for their food. The people who do manage to get in and order can't get back out so it just gets more crowded. The guy filling the bags and calling the order numbers seemed like he either shouldn't be doing that or he was brand new and needed more training.
The burger was great, but WAY overpriced and not worth the hassle of trying to order at this location.

I must tell you of a disturbing sight I saw.
While washing my own hands in the bathroom across from Smashburger, I noticed some struggling to the right of me. I turned and saw a Smashburger employee (shirt, hat, and logos worn proudly) remove his shoe and, using the flexibility of a broken lawn chair, place his bare foot into the sink.
Not just any sink.
THE HAND SINK.
He then “washed” his foot, did not dry it, slid it straight back into his shoe, and walked away without washing his hands, like this was completely normal behavior.
I’m unsure if he was heading back to make a Smash Toe Jam Burger using his feet and whatever new fungus had just transferred to his hands, but I was genuinely blown away. I immediately walked to the opposite end of the terminal to rethink my food decisions and set even newer New Year’s goals I didn’t know I needed.
Yes, I understand there could be a sink in the back of the restaurant. However, considering 99% of the world already doesn’t wash their hands properly, I’m not betting my digestive system on this guy being the chosen one.
Please be advised of this health hazard and spend your money somewhere else... unless foot fungus in your food is what you’re after

As good as it gets for airport food. You can have a double smash burger with cheese and fries for under $20, and it's actually delicious. Beers were the cheapest I've found at an airport too. I was ordering 20 Oz draft craft beers for about $12, cheaper than a pint at most airport places. Sure you can save some money by getting out of the airport, but this is a perfectly reasonable place to stop for a bite and a brew in between flights. Service was fast and friendly, the place is a bit small and crowded but they do an excellent job with the space they have. If you ever have a couple hours of down time at the Denver Airport you will be thankful this place exists.

The saddest 20.00 burger I have ever eaten. It’s about the size of a regular cheeseburger from McDonald’s, fries were old and Luke warm. Bread was stale and hard and burger had obviously sat for a while in the warmer. I was the only customer in line and the cook stood there waiting, once I seen the burger I knew why, he cooked it a hour ago and needed to give the illusion that he needed 10 minutes to cook it. This place is a scam.

Let me save you some money and get you a better meal and experience: turn around, go back to the central atrium, buy a burger from McDonald's.
Smash burger single. Patty was 2/3 the size of the bun, very crunchy (I know smash burgers are supposed to be slightly crispy, but this had a 2mm thick crust from having been left on the griddle waaaay too long), fries were soggy and cold, and the bag of veggies was limp. One credit I can give is that the no-cheese request was honored for my kid.
