Many folks compare Shake Shack to In N Out but I would compare Shake Shack to Five Guys instead because the menu options for their burgers are similar.
FOOD/PRICES:
You can choose from a variety of burgers (bacon, mushrooms, and cherry peppers), chicken sandwiches, hot dogs, crinkle fries, shakes made from custard, and beer and soft drinks. Prices range from $3-10 and because there are no combos, your bill may end up being pricier than expected.
QUALITY:
The food is made to order and you can taste the freshness of the ingredients. The strawberry shake was tasty and the chocolate shake was too chocolate-y. Not a fan of how thick the shakes were though. French fries were whatevs in my opinion. Hoping to try the cheese fries next time.
CUSTOMER SERVICE:
The cashier was friendly and somewhat helpful with the menu. Nothing super great and nothing bad.
ENVIRONMENT:
More restaurant type feel than fast food.
Overall, I would not come to Shake Shack if I wanted "just" a burger. I'd go to In N Out first - better prices and great quality too. Shake Shack would be more of a special treat due to the prices.
