You can't fault the diner for being clean and well, diner-like in its decor. I think I like the concept of a diner more than the idea of eating in one! At any rate, I found myself looking for a quick dinner. I ordered the chili which apparently has not changed since 1948. Same ingredients. I did ask what that meant: do they cook it in lard? Using the same methodology as 1948? What are these ingredients? The server had no clue and had to go back and check. In the end, I ordered it. It was ok.
I don't think I will come back. They definitely do need to better educate their servers on what the dishes are and what's in them. I'm sure most are no brainers but when you advertise on the menu the recipe has not changed since 1948, it will not hurt to be prepared to answer related questions.
