A neighbourhood bakery on Rue de Montmorency

Boulangerie Nicolas Flamel is an independent bakery in Les Halles, and what you notice walking in is how much of the trade is local: the same faces at the counter through the day, a small room with a view into the kitchen, and a counter stacked with viennoiseries, breads and lunch items.

The croissant is the thing to order first: crisp on the outside, soft and buttery within, and the pistachio version carries a rich pistachio flavour that makes it worth a second purchase. The pain au chocolat comes with a generous filling, and the Baguette de Tradition stays crusty and soft inside even bought late in the day. For something savoury, the croque-monsieur, standard or veggie, is cheesy and satisfying, and the staff will heat it for you.

Sweet things beyond the croissants hold their own. The praline flan is dense and sweet, a raspberry tart on a pistachio base pairs fruit with nuts, and a slice of red velvet loaf stays moist with raspberries adding a tart edge. Pastries ordered in advance for a celebration come out as asked, including the raspberry and Nutella croissants.

There are about eight places to sit, so breakfast or a quick lunch here is easy, and the counter staff are welcoming and speak English. Prices are reasonable for Paris: a croissant and a coffee is a small spend, and a baguette, a slice of loaf and a cake together came to very little.

Come earlier in the day for the freshest viennoiseries.

The pick list

What to bring home

  1. Croissant

    The plain croissant is the one to get first: crisp outside, soft and buttery within, and the best many have had in Paris.

  2. Pain au chocolat

    The chocolate croissants are soft with a generous filling, and one visitor called them the best in the world.

  3. Baguette de Tradition

    The traditional baguette is the one to get first here, and it holds its crust and soft crumb even when bought late in the day.

  4. Pistachio croissant

    The pistachio version has a rich pistachio flavour and is one of the items to try here.

  5. Croque-monsieur

    Both the standard and the veggie croque-monsieur are cheesy and satisfying, and the staff will heat one up on request.

Who is this for

This bakery suits anyone staying in Les Halles or the Marais who wants a proper Parisian breakfast without a long detour, since it opens at 7 am and has a handful of seats. It also works for a quick lunch stop, with croque-monsieur and sandwiches to take away or eat in. And if you are putting together a picnic or a drive home, the croissants and baguette travel well.

If you need a full shop or a late-night run rather than pastries, Supermarché G20 on Rue du Grenier-Saint-Lazare keeps Les Halles fed until 11 pm every night.

The verdict

It is a solid neighbourhood bakery rather than a destination in its own right, but for a fresh croissant, a baguette and a coffee at Paris prices it does the job for anyone nearby.
