There's a lot of stuff to buy in the 3rd, mainly in the side streets of the upper Marais down near the 4th. Of particular interest are the large number of men's clothing stores on rue de Turenne.

• Au Réparateur de Bicyclettes, 44, boul de Sébastopol (Métro: Rambuteau), ☏ +33 1 48 04 51 19. M-Sa, 10:00-20:00. If you would rather have a funkier bike than the ones you can rent from the RATP you would do a lot worse than checking out this little bicycle repair shop which also offers a wide range of new and used bikes. Their specialty in new bikes is Dutch and English bicycles, but some of the really nice ones are by the American company, Scott. Used bikes, €75+. 
• Marché du Temple. 

• Camille, 24, rue des Francs-Bourgeois, ☏ +33 1 42 72 20 50. Fantastic fresh French food. It is worth the wait. €40. 
• Chez Janou, 2, Rue Roger Verlhomme, ☏ +33 1 42 72 28 41. Chez Janou has such a pretty location that it's worth an evening visit just for that. But the food and atmosphere are also amazing. Vegetarians be warned, the tortellini is not the token veggie dish; there isn't one. €18. 
• Page 35, 4, rue du Parc Royal, ☏ +33 1 44 54 35 35. The name apparently refers to some section of some newspaper or another apparently with social listings. The carte features fantastic crêpe opportunities making this a must for lunch or lingering over a carafe or two of the house wine. €8. 
• Le Petit Marché, 9, rue de Béarn (Métro: Chemin Vert), ☏ +33 1 42 72 06 67. Daily, noon-02:00. This is one of those charming little Parisian bistros which is off on its own a little. The wait staff couldn't possibly be friendlier so this is a good place to bring people to show them how nice Parisian dining can be. The food is in a higher class than the price range, and the folks who work here have an easy collegial or even familial way with each other, and with frequent guests. 
• Le Potager du Marais, 22 rue Rambuteau (Métro: Les Halles), ☏ +33 1 42 74 24 66. A 100% vegetarian restaurant specialized in re-creating the French country dining experience without any of the meat. Menus for around €15. 

• Andy Wahloo, 69 rue des Gravilliers, ☏ +33 1 42 71 20 38. Andy Wahloo apparently means "I don't have anything" in Arabic. The Moroccan artist who owns this place certainly means it as a play on words having done the decor as a Moorish take on Andy Warhol. 
• Les Arts et Métiers, 51 rue Turbigo, ☏ +33 1 48 87 83 25. An updated but otherwise standard Brasserie, the draw here is the crowd: young trendy locals love the place. 
• L'Attirail, 9, rue du Maire, ☏ +33 1 42 72 44 42. Cool bar/club with concerts ranging from Jazz Manouche to contemporary swing. 
• Café des Musées, 49, rue de Turenne, ☏ +33 1 42 72 96 17. A bog standard and absolutely unpretentious bistro, the des Musées is a great place to cool your heels over a glass or two of red or white after stomping around the Marais all day. 
• Café Solo, 6, rue Dupuis. On a newly car-free street, the Solo has a huge music collection which they are in the process of selling off at €6 per CD. 
• Les Enfants Rouge, 9, rue de Beauce, ☏ +33 1 48 87 80 61. This one is makes for another tough call between the Eat and Drink sections. It's a completely traditional French bistro with a popular bar in the evenings. 
• Léonard, 57, rue De Turbigo, ☏ +33 1 48 04 07 55. If you like trendy décor this is your joint. Free Wi-Fi. 
• La Perle, rue Vieille du Temple/rue de la Perle. A small corner café-bar well-known to the trendy people of Le Marais. Dozens of young and old people gather here every evening, especially on weekends. There are also few other cool bars to enjoy on the rue Vieille du Temple. 
• The Quiet Man, 5, rue des Haudriettes, ☏ +33 1 48 04 02 77. This Irish pub has sessions and Irish music almost (but not quite) nightly. The atmosphere is tops for the genre.
