Shake Shack's Defining Features:

Modern restaurant setting: Shake Shack's restaurant was a rustic looking space, similar to a Chipotle. The chairs, tables, and walls were constructed in patterns of wood and metal.

Waste assistants: In normal fast food restaurants, customers are expected to dispose of trash by themselves. At Shake Shack, there was an employee at the trash cans, so the customer would simply hand the tray to the employee.

Combination of high class food and fast food: Shack Shack's focus is on quality over quantity. While a chain like McDonald's provides fast service, the quality is cheap and basic. In particular, Shake Shack's burger bun and the shakes are the "wow factor."

Lessons Learned:

Cater to the individual: An individually focused experience increases customer satisfaction in the long run

Create a high-class environment: Surrounding the customers with a seemingly expensive space makes tham appreciate the food (or any products) even more.

Provide an affordable, yet premium, product or service: The pricing of Shake Shack's burgers falls between cheap and expensive. They are more expensive than classic chain restaurant burgers, but cheaper than gourmet burgers. Shake Shack has a reputation of high quality food and defining products, such as their classic burgers, shakes, and crinkle-cut fries.

How can companies be like them?

Other fast food chains can take a page out of Shake Shack's book by focusing on customer service, classy and comfortable eating spaces, and low price relative to the quality. These are easily implementable business tactics that make a huge difference on a large scale of consumer attraction and satisfaction.
