I come from a Polish family that always cooked traditional food at home.
All I can say is that Polenez comes the closest to what I ate at home of any Polish restaurant I have ever been to. The food is just like what my grandmother made, and we still make. The pierogi were soft, served with sour cream and apple sauce. The biguse (hunter's stew) was full of saurkraut, mushrooms, and sausage was simmered to perfection. I don't usually like golobki (stuffed cabbage), but Polenez kept the tomato sauce under control. It complimented rather than overwhelmed the cabbage and meat. The fried lake perch were much larger than most and were a deep golden brown without being overcooked.
Polenez was clean (I think you could do surgery in the bathroom it is so clean) straightforward, and delicious. The only pierogi I like better are the ones my wife makes.
The price was reasonable, and the service was friendly. Since my daughter lives in Milwaukee I will be a frequent visitor to Polenez.
If you like simple Polish food you can't beat Polenez.
"A quartet of Pierogi makes a fine start to a Polonez meal. Their slightly-chewy skin is fork-tender, and the filling is moist and aromatic. Here are two each of sauerkraut-filled and potato-cheese."
"We love a fish fry of lake perch, especially when the elegant filets are accompanied by wafer-thin potato pancakes."
"Sliwowica -- plum brandy -- is the traditional digestif for after (or before) a good Polish meal. It looks like water, but it packs a high-proof punch."
"When Debbie the waitress saw me taking pictures of everything we ate, she suggested that she should take a picture of us, too. Here we are against one of the murals that decorates the interior."
"Not just a place to eat, Polonez is a community gathering center for occasions of all kinds."
