Higuma is an inexpensive Japanese noodle shop serving Udon, Ramen, and Tempura amongst other standards of Japanese cuisine. The food is a good deal and right down the street from the Place de l'Opéra. Situated in a small enclave of Japanese shops and restaurants, Higuma makes for a great lunch between sight-seeing stops. A meal here costs about 10 €, so it`s acceptable:)
