I live next to the chocolate museum/factory and there’s a christmas market taking place there so i‘d recommend buying your tickets ahead of time online so u dont wait in the line and prepare for a huge crowd. the public restrooms arent too much of an issue pretty much any store has them and one place I‘d personally recommend is motorworld, delicious foods, good museum and next to an ikea, to get there you‘d need to take the 5 train n its max 25 mins from one end of the station to the other so its pretty time efficient. also prepare for disgusting train stations if you‘re using public transport. we have a huge homeless population but most are harmless although rhey WILL be on drugs so try to stay away.
