New Yorkers sharpen their skates at Rockefeller Square, and those in Washington DC do their ice laps in the sculpture park of the National Gallery, so it's only natural that Varsovians would turn their triple salchows in the shadow of the Palace of Culture & Science. Ice time is free if you have your own skates; if not you can rent some for 10zł an hour or 5zł for 30 mins. The rink stays open as long as the weather stays cold (usually until the end of February) and bear in mind there is a break in the icy action between 13:00-14:00 and 17:00-18:00.
