What to buy at Aux Castelblangeois

Aux Castelblangeois is an independent bakery and pastry shop on Rue Saint-Honoré in Les Halles, a few minutes from the Louvre. The window display faces the street, and novelty-shaped cakes sit among the pastries.

The baguette sandwiches are what to order. Salmon, Caesar, Energy and ham come on bread with a proper crust, filled generously. The croissants are made with pure butter, and the pistachio éclair has a very thin coating and is not too sweet. The trompe-l'oeil pastries are novelty-shaped and not too sweet; the pear and pistachio tart is the more traditional option.

Inside, the shop is cramped. There are narrow standing tables fixed to the wall, maybe 15 to 20 cm deep, where you can eat a quick bite, but most of what leaves the door is takeaway. Payment is old-fashioned at the cashier, with the amount written on a slip of paper. If you want to sit somewhere green with your sandwich, the Tuileries is the obvious direction.

Prices sit below what you would expect this close to the Louvre: a pear tart at €3.60, a round of sandwiches and a chocolate fondant for under €16. Come at lunch and the queue looks longer than it is, because the counter moves fast; come late in the afternoon and the trays are thinning out, so the éclair you wanted may be gone. No coffee is served.

The shop suits anyone who wants a real sandwich and a pastry to carry to the river or the gardens.

What to look for

The pick list

What to bring home

  1. Baguette sandwiches

    The salmon, Caesar, Energy and ham baguette sandwiches are the ones to get.

  2. Croissants

    The croissants are the best in Paris.

  3. Pistachio éclair

    The pistachio éclair is the one people keep coming back for.

  4. Tarte poire pistache

    The pear and pistachio tart, priced at €3.60, is a pastry that has drawn attention. It features pears and what appears to be almond flour on a shortcrust pastry.

  5. Trompe-l'oeil pastries

    The novelty-shaped cakes and trompe-l'oeil pastries are not too sweet, with a very thin coating.

Who is this for

This suits anyone heading to the Louvre or the Tuileries who wants a baguette sandwich and a pastry to eat outside. It also works for an arrival off the train who needs breakfast at 6:45 am on a weekday. And if you are hunting novelty pastries to photograph before eating them, the trompe-l'oeil pastries are worth a look.

If you need provisions late at night rather than a sandwich at lunch, Panier Sympa on the same street stays open until 1 AM on weekends.

The verdict

The sandwiches and pastries hold up against anything in the area, so it is a swing-by for the food rather than a place to linger.
