Playing chess on the Stockwell Street University of Greenwich roof garden

Does London have a better place for a game of chess than the University of Greenwich’s Stockwell Street roof garden? If so, please tell me about it. While smelling the sweet scents of spring flowers, you can pick mint, gaze at a part of Le Notre’s design for Greenwich Park and catch up on your plant idents. And if you want more of London to be like this, find a good landscape architect!
