Three and a half stars.
We've eaten here now a number of times now, they expanded the menu somewhat and they have 5 Polish beers to chose from.
A word about the Pierogis - which is what you probably should order if you never tried them. They offer a mixed plate with meat, mushroom, cheese which you can have either "boiled or fried".
Boiled doesn't sound good but it actually is: think steamed dumplings, the flavors of the stuffing comes through better without the oil.
I tried them both ways a few times and personally preferred boiled to fried - which I found a little too oily.
