What Polish foods do foreigners generally not take to?

Yes, red borsch can be also a hot/cold beverage, served in a glass or cup. see below


yes, that is why when I cook red borsch for myself, it contains sausage, beans, kasha. You don`t need white one.

I can think of a few restaurants that do that, with our without paszteciki.

I once travelled a lot to do countryside courses. Occassionally I dined at a certain forest restaurant where I had gypsy`s potato pancakes and a glass of hot red borsch which was doubly hot - temp and seasoning.. That combination of tastes was so unique that I remember it even now though it was in 1991 - 93. Wow.

There's a place in the starówka in Toruń that sells pizza (only two kinds, with mushroons or without), has everybody sitting at long tables (rare for Poland) and to drink only sells clear borscht in cups.

The queues are round the block sometimes.
