About Marugen Ramen: Our signature dish, 'Aged Soy Sauce Niku Soba,' features a soup simmered bowl-by-bowl in hand-held pots with pork, combined with chewy high-hydration noodles and traditional Japanese toppings like grated yuzu pepper and green onions. The key to the flavor is the 'Aged Soy Sauce Gaeshi,' a blend of three types of soy sauce. Popular variations include 'Ajitama Niku Soba' and 'Spicy Niku Soba.' The menu also includes a rich variety of tonkotsu, salt, and miso ramen.

Popular side dishes include 'Marugen Gyoza,' 'Iron Plate Egg Fried Rice,' and 'Delicious Fried Chicken,' as well as soft-serve ice cream for dessert. Our spacious restaurants provide counter, table, and tatami seating (in most locations) to ensure a relaxing dining experience for everyone from solo customers to families with children.
