Portillo's first hot dog stand (1963)
Dick Portillo opened a small hot dog trailer in Villa Park, Illinois, called The Dog House. He sold hot dogs for 15 cents each.
The stand grew into a second location, then a chain.
Portillo's became a regional chain with dozens of locations across several states.
A single food service license can be the start of a small neighborhood business or, rarely, something much larger.
