If you want to feel like a lucky human being, choose a random weekday afternoon, call a friend, and install yourselves in the tea salon at Jacques Genin. Order the millefeuille for which he is known and maybe an éclair as well. Oh, what the heck, get the lemon tart too. Try not to wince at the price of a pot of tea and sit back and relax, knowing that someone in the kitchen upstairs is assembling that famous napoleon to order (this is not one of those bricks that sits all day in a refrigerated case) and that soon it will be served to you, maybe by M. Genin himself.
On your way out buy some chocolates or, better yet, a sachet of caramels (mango passionfruit!) to take home.
Do not, I repeat, do not think of your dentist as you decide to have just one more before closing the package.
And by all means, do not be too hard on yourself when you open it again two minutes later.
Jacques Genin, 133 rue de Turenne, 75003 Paris +33 (0)1 45 77 29 01
