It's one of the largest pizza restaurant chaines in Poland. There are many Dominiums in Warsaw. The look and ambience are more or less the same everywhere as is the quality - just average. Don't expect the waiters to be very present and kind. They just bring you the stuff and take money when you've finished. Thin pastry is better that the thick or standard one. In general, there are many better places to have pizza in Warsaw. For example Pizza Hut is better and equally easy to find.
