3rd Arrondissement Specialty

I/O Café—named for the on/off buttons on a coffee machine—is a simple spot to pick up a cup of specialty coffee from Danish roaster La Cabra.

At 400 years old, the Marais-based Marché des Enfants Rouges is worth browsing whether you're hungry or not (you can always stock up on fresh-cut flowers, ephemera, and larder-worthy oils and preserves). But bring an appetite—you'll find a seemingly endless sprawl of food vendors hawking everything from tagines to crepes to hearty sandwiches. Our pick: Chez Taeko's stand, which serves delicious, authentic Japanese fare.

For more than 200 years, Goumanyat has been a go-to spot for Parisian chefs looking for hard-to-find ingredients and spices. They specialize in saffron, which is stored in huge glass jars behind the counter, and grown on their farm in Iran. They’re located in a fittingly historic space that was formerly an apothecary, but they keep very irregular hours, so it’s best to call ahead before you drop by.

This mini-chainlet is now five Paris locations strong (with two outposts in London), which makes a lot of sense: The bread really is distinguishably excellent, which in a place like Paris, says a lot. Though the sourdough loaves fly off the shelves, we love their nut breads—along with the fact that you can purchase by the half or quarter loaf if you can't take down the entire thing. There's usually a line, and while there's nothing to be done about that, you can always duck into La Cuisine de Bar instead. It's a sandwich shop next to the location in the 6th, where they make sandwiches from Poilâne bread. Other locations: Saint-Germain-des-Prés and Eiffel Tower district.

We like to take a detour here while shopping on Rue Vieille du Temple. Though the buckwheat crepes are the main draw, there’s a small shop attached to the café that sells jams, ciders, and delicious cheeses.
