Their burgers were sub-par. I was expecting In-N-Out burger on steroids but was disappointed. The burgers were not as flavorful as I thought. The Shack Burger was doused in Shack sauce but I could barely taste the sauce and the burger patty. The patty was tender and juicy but half way through my meal the burger had fallen apart and I ended up eating the rest with a fork. I can say I've tried Shake Shack but I will not be returning anytime soon.
