These are getting tougher....
I'm going to bet it is was an Italian restaurant -- but I dunno where...
odd architecture for nearly 100 years?
George, it looks like snow and salt on the walkway.
The architecture doesn't look enduring enough to have been there for 100 years.
We may need some more hints?

Give me enough clues and even I can find it!
Howza about Vogel's Restaurant in Whiting, Indiana and the specialty was Frogs Legs & Perch?
Maybe not -- this closed in 1997...
It does seem to fit (some of) the rest of your clues though...
Hold the presses... they also specialized in perch and frog-legs and they closed in 2007!
What about
Phil Smidt Restaurant -
