I forgot to say yesterday that we had lunch in the Garden Café, the ridiculously delicious café attached to, and indeed run by, the Garden Museum.   The orthodoxy is that museums cannot, and should not, run their own catering operations.   The Garden Museum transgresses this orthodoxy with style and profit (I am not going to pretend that it is cheap).   I have seldom had six such delicious starters – and ale – more than enough for three and a half of us to eat.
