Fast food at its best!! I had heard this compared to in n out a lot. People said this was like the east coast version with the limited menu and fresh ingredients. I grew up in southern California so in n out is one of my favorites... and really hard to beat in my book. But... i hate to say it... Shake Shack succeded. This place is great. We tried the the regular fries, cheese fries, the smoke shack burger and the shack stack. Every thing was delicious! The cheese stuffed mushroom on the shake stack burger was amazing! I will for sure be back! Now they just need to open a location off the strip for us locals!
