How did I forget this? I grew near this fast food chain of 1 store. Great roast beef sandwiches, and I mean great. French fries with melted cheese.
Here is a site with a map of where they are:

If you look at Manhattan Beach, across Sheepshead Bay, look for Coleridge Street. I grew up on the ocean block.
I just remembered Roll-n-Roaster because my sister and her boyfriend ate at their (after 33 years!) second location that just opened in manhattan at 3rd Ave. & 11th St. I'll have to make a run there soon.
