Gilly's!

According to their website, the diner (which dates to 1940) was one of only five of its kind built by the Worcester Diner Company and is currently the only one still in full operation. Before it found it's permanent home on Fleet Street in the shadow of the High/Hanover Parking Garage, Gilly's PM Lunch was a movable wagon that was pulled first by horse, then tractor (pictured here) and finally by truck.  After it was parked in place, a small addition was added along the side of the lunch cart.  Responding to health code requests, a new larger addition was added and the once still visible truck that was the last means of mobilization for Gilly's was removed.  

In spite of the recent changes, Gilly's still has interior and exterior integrity that, with its greasy hamburgers and other like foods, make stepping inside in the early hours of the morning like stepping back into the Eisenhower era...only greasier.
