Shake Shack (2001)
Shake Shack started as a hot dog cart in Madison Square Park, New York. The cart was so popular it became a permanent kiosk, then a chain.
The kiosk opened in 2004, drawing long lines.
Shake Shack grew to a global fast-casual chain with hundreds of locations.
Shows how a small mobile food operation can transition successfully to a permanent restaurant, similar to Tamales La Reina's path.
