The burgers are tasty, but definitely a bit overpriced. The burgers strike me as being a cross between In-N-Out (freshness) and Smashburger (burger styles). Their most basic burger is the Single ShackBurger, which is about $5 and surprisingly filling and delicious. They have some basic crinkle fries that you can either get plain or throw some melted cheese on. It takes about 10 minutes or so for them to get your food ready, and they give you a little buzzer so you can know when you can pick up your food.
I'd recommend this place if you're confined to this the area and in the mood for a tasty burger. You can probably get a larger burger for a lower price elsewhere, but these burgers will not disappoint.
