Trying their Polish plate is a good place to start here. I can not attest to the authenticity of the food but I have come settle on their Hungarian goulash between two potato pancakes. I have yet to eat the whole serving and end up taking some home. They have pierogi and stuffed cabbage and Polish beers and liquors. For desert, they bring out a tray of each of the items on the menu.
The place is clean and contemporary looking with a bar area and a dining area with booths and tables.
The staff speaks Polish to most of the customers that appear to be regulars. I have found the service inconsistent even when the same server takes care of you.
