Where in London (UK) can I buy edible gold leaf/powder or lustre?!
Answers: Good Indian food shops should stock it, also Harrods food hall and Fortnum and Masons...but the Indian shops will probably have the better price. I would telephone a few and ask first..saves a lot of time and walking around.
Loads of Indian shops have it as we use it to decorate Indian sweets. Silver is popular but they will tell you where you can get gold
Harrods.
