Burger chain Shake Shack just announced plans to expand to 1,500 stores. The fast casual sector is growing much quicker than other parts of the restaurant industry.

“The American consumer loves to try new things, especially if we’re already familiar with it.”

Depending on how to measure, the minimum wage should be closer to $12, or even $19.

Its valuation is huge for a new burger chain with fewer than 100 stores.
