This is *the* place to go for authentic Polish cuisine! I've eaten here several times and have brought friends and family (all of whom have had a pleasant experience). The staff are indeed all Polish and even offer Polish language lessons on the side that you can sign up for at the restaurant.
The food is wonderful and if you haven't been before I would recommend their sampler platter which includes a hearty portion of perogies, cabbage roll, and meat. They offer varying specials at lunch. For their dinner menu they add their potato pancakes to the menu for an appetizer that is a must!
The staff is extremely friendly and helpful. I also enjoy that they pay attention to their customers, and remember me each time I come in...even the beer that I like with my meal. Speaking of which they also carry imported Polish beer that tastes light but is in fact quite strong for a very reasonable price! The decor is low key, unassuming, and inviting. It's the perfect place to relax and enjoy a great casual meal with friends.
