I was sent these pictures by my old man, who visited on Friday.
The Frazer diner is a 1935 O’Mahony, originally located in and named the Paoli diner. (Paoli is also the home of the Philadelphia curling club, where I’ve spent a lot of time). It was moved in 1957 to its current location, just down the road, in Frazer. It was renovated/restored in 2002.
A photo of it before the work was done, showing the old awnings, can be found at:

The Charcoal Pit- original location – North Wilmington
The Charcoal Pit Tradition dates back to September 1956 when it first opened its doors. The “Pit” – referred to by loyal customers, became such an instant success that only after three months from the grand opening, it was decided to build more room for its long line of hungry customers. The “Pit” went from a small four table and a counter burger joint to a 115 customer-seating establishment.

I really got to make it there!!!!
That is such an incredibly nice diner!
I remember going to the Charcoal Pit as a kid. Great to see it is still around!
Had dinner at The Charcoal Pit following the John Prine concert at the Grand Opera House. Two great pieces of Americana in one night. The burgers and fries were straight out of a Norman Rockwell cover. The classic black and white milkshake was so thick you could stand a spoon in it. It was served in the traditional metal shaker. I had to explain to my dining companion that the spoon was important functionally in order to transfer the shake into the glass. The one sad thing is that it was so quiet at 11:30 on a Saturday night.
