This whole potato thing is borrowed from Ruthenian peasants, and the menu indicates as much (ruskie pierogi) when you order anything with potatoes and/or cheese in a pierogi at a restaurant in Poland. In the many years I traveled around Poland or lived there, I have never seen anyone make potato pierogis at home.

in general, polish culture in western pennsylvania has been watered down in the pan-slav-milieu of slovaks, czechs, russians and poles that often lived in the same mining and steel mill towns in the appalachians – polish americans eat czech dishes that they think are polish (and vice versa, too, i’m sure). whatever remains of polish culture in western PA and OH now is about as chinese as general tso’s chicken — if you go to poland and order any pierogis with potatoes they are called ruskie pierogi (e.g. russian pierogi)… yet pittsburghers of polish descent have somehow become convinced that cheese and potato pierogis are a staple in poland.

your best bet in america is to go to brooklyn or chicago if you want good authentic polish food (though there are a couple good ones in boston).

nothing on this menu is anything that anyone in poland would ever eat. it really makes me wonder whether the chefs have even ever eaten any authentic polish food whatsoever…. makes sense that they are from the mid-west, this is like the frito pie of pierogis.
