The Branchburg Diner Incognito

I passed the Branchburg Diner recently, and, to my surprise, the name and the sign had changed.

The sign now says "25 Burgers." I don't know if that means they are selling burgers for $0.25, or if it means they are selling 25 different kinds of burgers. I had neither the time nor the inclination to stop and find out.
