CHESTNUT HILL (CBS) – A new fast food chain with a cult following along the East Coast has opened outside of Boston.

Several people were waiting outside the Shake Shack when it opened its doors in The Street Chestnut Hill on Route 9 Wednesday morning.

The shack bills itself as a modern roadside burger stand that started in 2001 as a food cart in Madison Square Park in Manhattan.

The stand drew long lines and eventually expanded to stores throughout New York, Connecticut, Washington D.C. and Florida.

In addition to shakes, the chain sells burgers, frozen custard, beer and wine.  They even offer dog treats.
