Here is my own experience.
I called them for ordering in take away. When a member of the staff realised i was speaking in english he hung up the phone.
Then i tried 3 times more and i could not reach anyone.
My lovely polish girlfriend called with her number 10 mn later and finally could made our order.
An hour after, we got delivered. Surpringly because at that time we were living in Jana Pawla street too. Probably 1 km max from the restorant.
Food was obviously half cold and honestly tastless.
We were expecting a lot from this new restorant close to our home but our first order was our last.
