The area around the Opéra Garnier is intense. Walking here on a Saturday afternoon can be a bit of a nightmare. You always have to find your way between Chinese tour buses and shopping bags that pedestrians carry large shopping bags on the sidewalks that always seem to be too narrow. However, when I do go on an expedition to this area I make sure to go for an early after-shopping dinner in the rue Sainte Anne, hidden just behind all the large boulevards.
The rue Sainte Anne is the heart of the Japanese district of Paris, or actually rather a district by itself. I cannot think of a restaurant or shop in this street that does not in any way relate to Japan. Even the boulangerie mixes green tea into its pastries. Some Korean restaurants break the Japanese hegemony, but they remain a minority. Also the Taiwanese place called 37m², a name inspired by its surface, is a nice place to have bubble tea.
It doesn’t matter that much where you go for your meal, as many restaurants are quite similar. Don’t necessarily go there for sushi but rather for ramen and other hot dishes.
My favourite restaurant is actually not on the rue Sainte Anne, but a few streets further on rue d’Argentueil. You can easily spot Sanukiya by its permanent queue. They make their noodles right before your eyes and their other ingredients are just as fresh, making you eat their half-raw eggs without any problem.
