Isonoya is a seafood restaurant in the Kami-dori area of Kitashinchi in Osaka, close to the Midosuji main street, with private rooms, counter seats, and table seats. Its signature dish is hamaguri nabe, made with large clams and finished by adding somen noodles to the broth. The restaurant also serves sashimi platters and grilled oysters with butter and soy sauce. The foreign-language menu differs from the Japanese menu in both items and prices, so check the Japanese menu before ordering.
