Now we moved back to Wisconsin after a 26 year absence. We used to have a cottage in Tomahawk, Wisconsin and knew all the best Supper clubs. These are Brandy old fashioned drinks, relish trays, prime rib on Saturdays. We went to Door county this weekend it
Was all there! walleye, prime rib, shrimp, sheesh curds. Mmmmmm
Cheese curds too late to edit
There’s an awesome documentary, “Old Fashioned: The Story of the Wisconsin Supper Club,” which came out a few years ago. I’ve seen it on our local PBS station here in Chicago.
Having grown up in Wisconsin, supper clubs are near and dear to my heart. 
Where in Wisconsin are you?
If you’re near Milwaukee, the place you’re looking for is The Packing House.
If you pop a state west, we have Wiederholt’s Supper Club in the lovely wee town of Miesville, Minnesota. City population of 122. There’s a bank, a gas station, bar, church and supper club. A bump in the road. Yet, if I happen to drive by on a Friday or Saturday night, it’s absolutely packed.
I have never had dinner there, but my mom remembers going there in the late 50’s, early 60’s when they’d backroad to LaCrosse.
my parents must have eaten at every one between Sheboygan and the Dells in the early 50s; Get all dressed up and go with anotheer couple, and haul me along and make me shut up keep my elbows off the table.
I dinn’t know they were Wisconsinana.
I too grew up thinking supper clubs were universal. Here in Sheboygan County I loved dining at Johnny’s, Rupp’s, Hoffman’s at Riverdale, Fin and Feather, and Company F, to name but a few. Road trips around the state led us to Ray Radigan’s and the Pyramid. Along with countless others whose names escape me.
It’ll be a treat to go back to a supper club once this covid PITA is over.
How Wisconsin am I? When we took our dates out for dinner before the Homecoming dance in high school, we went to a supper club (The River’s Bend, in Green Bay).
For the benefit of us, the untutored masses, what distinguishes a supper club from any other type of dining establishment?
The only time I’ve ever heard of one, it was when John Cleese and Maggie Smith recommended one to Kermit and Piggy.
The link that @kitap shared has a pretty good summary. Others will add to this, but the general characteristics of a Wisconsin supper club are:
- It’s a bar and sit-down restaurant, nearly always family-owned
- Drinks are focused on beer, and brandy-based cocktails (Brandy Old Fashioneds, Brandy Alexanders)
- Relish trays, cheese and crackers, and deep-fried cheese curds as key appetizers
- Menu has both dinners and sandwiches, with certain daily specials (most importantly, and invariably, a fish fry on Fridays)
- Typically a “north woods” decor, often with wood paneling, and stuffed fish and deer heads on the walls
Also, note that, despite the name, they aren’t actual clubs, and anyone can dine there.
Also, this 2015 article from the Chicago Tribune (probably paywalled) has some truisms about Wisconsin supper clubs:
Yeah, here in SoCal,we just call those “restaurants.” Family-owned ones being rare notwithstanding.
So it’s just sort of a restaurant style, like Coney Islands in Michigan.
My guess is it’s more than that. We moved Midwest from NYC/New England and I can’t find any place that’s a diner. I can find restaurants that serve similar food, and even a somewhat similar atmosphere, but it’s not a diner. So, I’m guessing there is is some intangible quality that makes a restaurant a supper club.
Now that I’m here in Chicagoland, I’m intrigued!
Point taken. But we laid-back moondoggie-types even consider “diners” to be “restaurants.”
Couple more brandy old fashioned and you’ll be ordering another plate of sheesh curds.
Ope! I said “sheese curds.” Cri-hey! 
I’ve been to this one in Wausau a few times, though sadly it has since closed. It definitely had a wood panel and cocktails feel.
I like that it’s located on Rib Mountain Drive.
