I replied in the other thread.
I’m pretty sure you are thinking of Pine Ridge on Lake Sissabagama near Stone Lake, WI. I included a link in the other thread where you can see pics of the picnic tables. They have added on, so there are more small tables than picnic tables now.

It is by far, my favorite fish fry and broasted chicken. The food is excellent. They do it on both Friday and Sunday because they have so much demand. All you can eat fish – deep fried or broiled, all you can eat broasted chicken, french fries (or choice of potato), cole slaw, and fry bread (careful, this stuff is good, but it’s filling so you won’t be able to eat as much of the other stuff). Each person also gets one complimentary glass of wine. It’s the only restaurant I’ve ever seen where people tailgate in the parking lot while waiting to get a table. And the service is awesome! The servers have no problem bringing you a 3rd chicken breast or a 4th batch of fish, they want you to enjoy yourself. But they do keep bringing that irresistibly delicious fry bread in an attempt to fill me up.
Pine Ridge is only a restaurant now. The resort and cabins were all sold off some time ago. Only open Thu. – Sun. Fish only on Fri. and Sun. and I’ve heard their Saturday Prime Rib is excellent also, but I have yet to go on Saturday.
