I recently had the opportunity to try this burger joint in Denver, and must admit that I enjoyed it much more than I thought I would.
Had the classic Smashburger, which came on an egg bun, with lettuce, tomatoes, pickles, onions and a 1/3 pound patty, and some Smashsauce.
*Egg bun (nice and sturdy and held the burger together, for the most part)
*1/3 pound beef patty (this was just the right thickness ratio for the hefty egg bun)
*Smashsauce (which is nice and savory, and none too sweet)
*Red onions (which were too raw)
*Messy (this is not a burger you can eat while driving)
*Pickles were rubbery and too salty (minor complaint)
All in all a very good burger.
Tastes like what the "Six-Dollar Burger" at Carl's Jr. should if it was done right.
It's a nice bridge between generic fast-food burger and more high-end gourmet burgers.
By the way, pass on the french fries and get the haystack onions which are amazingly addictive. Oh, and the root beer float ain't too shabby a way to wash it all down with.
I don't think there is any "big secret" as to what the Smashsauce is (contrary to the claims of the restaurant).
Smashsauce is basically a variation of thousand island dressing -- i.e., some combo of ketchup, mayo and relish.
But what makes the Smashsauce a bit different than, say McDonald's "special sauce" which is also just a variation of thousand island dressing, is that the Smashsauce is a bit more tart. I think they must add more ketchup than mayo, or maybe perk it up with some vinegar or lemon juice.
I doubt the pickles are homemade. They were just too salty, and to add insult to injury they were also flabby. Not crunchy at all. It was like biting into a wad of soft tissue soaked in brine solution.
As to the onions, yeah I guess it's a personal thing. But the patty was so well carmelized (from the "smashing" process) that the bitter rawness of the onions was a bad contrast. Again, probably a personal thing.
As an aside, watching them make my burger I'm almost inspried to cook my next hamburger patty using my panini grill ...
Will simply post to agree with your comments. An extremely tasty burger (I suspect a sausage-like fat content.. but who cares?), a unique concept and pretty good execution. Fries are <yawn> and you can't order a nice bottle of wine to compliment your $10 meal but it's good stuff!
