At the very centre of Giszowiec, if you're lucky you may be able to catch one of the frequent events held here (check their website to see what's on). The Dworek Pod Lipami restaurant is also here and represents the best place to eat in the area. They also sell some additional English-language info including the 'History of Giszowiec'.
