Mellonhead, thanks for starting this post. My parents are coming in this weekend (though only Dad is going to the Auto Show) and we were thinking about Polish food so they would go home perfectly stuffed.
My dear, Ukrainian/Polish cleaning lady, Luba, recommended that we try one of these two spots for the buffet. She swears that Old Warsaw is as good as her own grandmother's cooking and a more upscale atmosphere than traditional buffets, and that Czerwone Jabluszko (Red Apple) is also great food for the price, though not nearly as nice.
Old Warsaw
4750 N Harlem Ave (Harlem & Lawrence)
Harwood Heights, IL 60706
(708) 867-4500
Red Apple Buffet
3123 N Milwaukee Ave (near Belmont intersection)
Chicago, 60618
(773) 588-5781
I think we may try Old Warsaw this Sunday, since it will be easier to bring our toddler and preschooler just after naptime. But, I am interested in these other suggestions, as many of them would qualify as great cultural experiences, and thus great for out-of-towners looking for a different experience than they could ever get a home... particularly if home is in South Dakota, where approximately 7 first-generation Polish people live.
