Why are Polish restaurants not successful in the USA?

The concept of eating out is far from new to Polish culture - thee have been restaurants in Warsaw for centuries.

There was no need to eat out until foreign flavors arrived.

What a load of utter bollocks: from 1945 to 1989 the main meal of most people's day was eaten outside the house.

no it isn't when i was working in Poland years ago it was so normal to have lunch out that you could buy a 'season ticket' for the local restaurant or eat at the milk bar.

Like carrots and tomatoes in the C18? There were restaurants in Warsaw long before that. Try harder next time. The reason why Polish food isn't popular abroad is that it just isn't interesting enough to go beyond niche restaurants.

There were inns of various kinds [karczma, zajazd, oberża, wyszynek, gospoda, etc.] since the early middle ages, so I'd end the "concept of eating out" topic with that.

Again: the reason why Polish food isn't popular now is that it was literally impoverished over the decades of wars&occupation, like communism [when not many products were available in the shops, learn the history].

Real Polish cuisine consist of tons of fresh or cooked local vegetables, fruits [and many kinds of products like dżemy, marmolady, konfitury, powidła], many delicious soups, various kinds of venison [served with for example wine sauces], it was also famous for its large variety of fish dishes [and how many Polish fish dishes can you recall right now?], and has ones of the best desserts in the world, like my personal favorite cheesecake [which has NOTHING to do with the American cheesecake made from the liquid cream], I could go on and on, just look into real cookbooks or old Polish literature.

The reason why Polish dishes in modern restaurants are so bland is purely the ignorance of the cooks - but, thankfully, it's changing slowly.

yes i think a similar thing happened with British cuisine, it is fine if made with the finest and freshest ingredients but ww2, years of rationing and the advent of factory farming put an end to that

It's hard to believe you live in America at times.

Americans don't appreciate bread, meat and cheese? Go away troll.

And lol at the sauerkraut comment. German cuisine is quite popular here so you're wrong about that too. Every BBQ party I've ever been to in my state served bratwursts with sauerkraut.
