If I go a week without going to Smashburger, it's honestly an off week.
There is just something special about their burgers. My go to is always the bacon avocado club. Comes wuth bacon and avocado (obviously) and ranch drizzled on top. 10/10 for sure.
Also, go with the smash fries. They're tossed in Olive oil and rosemary and SO good.
Lastly, the shakes are amazing as well. I would personally recommend the butterfinger or salted caramel.
