It’s amazing to find such a restaurant not far from the famous and luxurious Place Vendôme. The food is excellent and reasonably priced (about €10 without drink which is very low for this area). What's more, the courses are generous and the service is quick and efficient.
This is an ideal place for a quick and inexpensive meal in the city centre. They serve ramen, katsudon, gyozas, katsu and noodles, and they have an open kitchen so you can watch your meal being prepared. I always order the same thing: Katsu Don (rice with egg, chicken and condiments for €8.50).
They don’t accept credit cards so remember to bring cash.
