I loves me a greasy spoon! Diners are the best, and very hard to find now. There's a few left in my state. Some years ago, hubs and I had this hobby of driving around New England to find diners. It was fun! Love the style of the one you went to--that's exactly how I like to see them (the few that remain . . .

).
About 10 years ago, there was one that was well known in our parts, but the owner sold it to another chef. The new chef completely changed the menu into some sort of gourmet cooking menu, and guess what? It didn't last a year under the new ownership--epic fail.
Your REAL diner deserves another bow here.
