Do yourself a favour. Head to a grocery store for cheese, a baguette and some fresh berries. Stroll to Jardin du Palais Royal. Order a takeaway coffee from Café Kitsuné in the garden (their iced long blacks and salted chocolate cookie are life changing experiences). Take a seat and enjoy the surroundings of French locals sipping coffee amongst the flowers, with their feet perched up on the edge of the fountain. You’re welcome.
Note - repeat the above also at Place Des Vosges. Swap the takeaway coffee to one from Fragments, around the corner, and sit under a tree.
