I have Hannah to thank for this one. After a quick email exchange while she was in Hong Kong and I was in Paris, I was promptly reminded to visit one of her favourite breakfast spots in the 1st, Claus.
The 'Claus' set breakfast included coffee, fresh juice, bread with butter and jam of the day, a boiled egg and bircher muesli.
Alongside Rose Bakery, this was the best breakfast I had in Paris! Downstairs they also have a delightful selection of organic pantry staples, fresh jam, bread and pastries. I miss going here so much, and especially that feeling of being rugged up in a great cafe while it's absolutely freezing outside.
