Went here a few days after they opened a couple weeks ago. The "Euro-techno" architecture was pretty cool, kind of a ultra-modern Polish vibe to it. Tried a nice sampling of 4 or 5 different menu items, the pierogi were ridiculously good! I could not recommend them more (go for the meat or sauerkraut), the dessert, and the golumpki were also great.
The beer and liquor selection were pretty good, definitely going towards the vodka bar theme, hence being a Polish place. The bar tender was cool and entertaining after my buddy had one too many (I remember my first beer...). I spoke to the owner a few times, really cool guy who seems to know what he is doing. He was very open to comments and suggestions. My only real gripe was their prices were a little crazy, the food portions were a little small for the price and the mixed drinks were really pricey, stopped me from drinking too many. Maybe do drink specials?
Not many Polish joints in Phoenix, ill definitely be back.
