As a native West Coast person, it's shameful for me to admit, but I am in love with Shake Shack.
I have had Shake Shack while traveling in New York City. It was there that I fell in love with this chain.
Price: Much more expensive than In N Out or other chains like McD's.
Selection: a wide selection that includes burgers, hot dogs, milkshakes, etc.
Taste: I love their bread! I'm the type of person who goes for protein style but man, their bread is soft and delicious! Holds in all the juicy patty and gooooodies. I always order the SmokeShack! It has some peppers and bacon and that juicy patty, omg I'm like drooling as I think about it!
I have turned quite a few people onto this place. The most unfortunate thing is it is only in Vegas (for now)... when I'm here I annoy people by telling them I'm going to eat here every meal time...
