Maguroya Kurogin is a hidden gem in Osaka's Nippombashi area, known for its top-notch tuna dishes. This cozy spot offers a variety of fresh and delicious tuna sushi and sashimi options that will make any seafood lover's taste buds sing. With limited seating and a bustling atmosphere, it's worth the wait to indulge in some heavenly street-side food that's definitely worth the slightly higher price tag.
