The best volume of young girls in Warsaw can be found in the pedestrian paths of Parade Square in front of the Palace of Culture and Science and the shopping stores side of Marszałkowska street.
Warsaw has one of the best daygame areas of eastern europe because it contains several anchors for pedestrian traffic in a relatively small area: a huge mall (Złote Tarasy) directly connected to the primary railway station of Poland (Warszawa Centralna), a busy shopping street with top brands (Marszałkowska), one of the largest metro stations of Warsaw (Centrum) and the second largest city square in the European Union (Parade Square).
Chmielna and Nowy Świat streets are packed with bars and coffee shops suitable to be dating venues, they also have a decent pedestrian traffic so you can include them in you daygame route, specially during university season as many of the faculties are nearby.
Złote Tarasy and Warszawa Centralna are ideal for poor weather times, they carry so much pedestrian traffic that its worth going there even when the climate outside is perfect.
Best times to visit
Weather is ideal from May to September. Although university break is from july to september, the city keeps itself busy due to its large size so keep it in your list for those times.

I believe the best method of street game is the London Daygame Model. I recommend the key textbook Daygame Mastery. It's an encyclopedia of street game technique. For video, I suggest the infield instructional Daygame Overkill.
