My wife, mom, and I stayed at the Diament Plaza hotel and had dinner at Poziom 3 out of 4 nights we were there!! Although there are other good restaurants in Gliwice... this was the most authentic Silesian/Polish food... exactly what we were looking for....Their classic zur soup was fantastic. Also the potato pancakes, duck, dumplings were great. One of my favorites was the traditional pork belly dish called Himmelreich served on a bed of sauerkraut and mashed potatoes... out of this world. Lukasz... the head host took excellent care of us. The staff were all very welcoming and gracious. On our last night at the hotel, my wife and I were packing and felt like staying in the room, so we ordered dinner to the room and Lukasz brought it to us on white table cloth and candles. Very nice touch. Thank you so much for the excellent service!More
