RE: Ben's Shrimp
I don't know about Ben's but Chicago has long had neighborhood seafood shops where you can get fried shrimp or fish by the pound along with smoked or fresh fish. It seems that many of these had Scandinavian owners and I know that Frank Hansen's on Harlem has recently closed.
In Des Plaines there is a very busy shop called Don's Dock. It has it's roots from a Scandinavian fishing family in Door County Wisconsin. I often stop in and get a pound of fried shrimp and a bottle of Hoffman House seafood sauce. You can sit down and eat there or carry out. It's not a restaurant but they have tables and lots of folks have lunch there. They have fried fish and shrimp , fresh fish/shrimp, smoked and various daily specials. Nice family place. Give it a try. It's on Northwest Highway, west of Mannheim/Lee Street.
Do other cities have these kinds of places or is it a Chicago phenom that can be traced to Scandinavian immigrants???
