I went to the Smashburger Yelp event a couple weeks ago and was pretty impressed with the food and have been raving about those SmashFries since. The burgers were flavorful, not overly greasy, and the fries were cooked to perfection.
Unfortunately, that night gave an unrealistic expectation of what the chain really serves up- greasy burgers and old crunchy fries. The only thing that seemed to be as I remembered were the sweet potato fries.
We ordered the large burgers, something I won't recommend as they come on the same size bun- the patty is the only thing that's larger which makes it flop over the side of the bun condiment-less.
My burger was also served on a tray only half lined with paper, so I had straggling fries. The staff was kind enough the leave the expo ticket on my plate, too (yay fiber!). The tray liner was also soaked in grease, something that didn't happen on Yelp night- I double checked the photos. This is a shame since this location is a stone's throw away from Red Robin, In-n-Out and a couple other places.
TIP: Wear a Yelp shirt for good food.
