All true, but my ma-in-law's naleśniki with minced beef knock any crepe or blini I've ever had into a Polish cocked hat.
Are they close to "krokiety"?
Polish 'krokiety' are usually rolled pancakes filled with meat, cabbage, cheese or mushrooms, fried in breadcrumbs. They can take longer time to prepare, but they're definitely worth it. 'Krokiety' with cabbage and mushrooms are a traditional Christmas Eve meal, but they are also served for an everyday's dinner or lunch. They go very well with beetroot soup or mushroom sauce.
Krokiety: mushroom+sauerkraut, or meat
