One of my coworkers has family in Wisconsin and visits at least annually. He has a George Webb's t-shirt, so I assume that some of them are still open.
My grandparents thought George Webb was fine dining. Went there for their anniversary just about every year.

I just ate at one a year or 2 ago.
First I had heard of them.
