What dishes are considered upscale, served at 5 star Polish restaurants, 5 star hotels etc, foods that Polish upper class eats? The foods should at least partially be Polish in origin from Poland or Lithuania. Thank you.
Maybe check the menus of some restaurants like Sowa, Platter, Amaro - it's normally something like a posh version of pierogi, a posh version of some seasonal Polish soup, game, something involving grzyby and always a steak and a fish dish on menu.
The "upper class" of any country is rarely larger than 500 people, many of whom are out of that country at any given time.
If you mean restaurants frequented by the wealthier end of the middle classes (those that live in or near the capital anyway) there are a few. Amaro is popular (and booked solid long in advance). The menu above looks like one of theirs. Basically fusion food with some local ingredients.
This one is an old favourite of the elite. Its official name is Restauracja Belvedere, however the cognoscenti refer to it by another name. Basically classic European international food. Its website is here: belvedere.com.pl/en/home
There's also Fukier, famous in the 90s and 2000s for hair-raising prices, which has become a bit touristy now. Good food though.
La Squadra in Katowice, I remember it from the previous years, good Italian food from an Italian chef, affordable daily menu. The best and always the same tasting Focaccia I have ever eaten, and at the end the opportunity to look at a dozen Ferraris in one place.
