Hello ladies, wonder if you can help. I need to get hold of a set of plates / cups / napkins for my little one's birthday this weekend. Ideally with a car or train theme, Disney Cars or any transport theme really. Not Thomas the Tank Engine, as we had that last year. Any suggestions for a party shop selling these in Lewisham / Greenwich / Blackheath or even central London? Where else could I look? I checked out Amazon but they don't seem to do next day delivery on party accessories. Heeeelp!
