I’ve been to there 2or 3times when i go to shinjuku! the noodles are big portions, the soup is savory, not fatty, clear. inside the ramen shop is clean for ramen shop in shinjuku(no offence) and they got good service. if you don’t mind your breath smell bad, definitely recommend to add toppings of chives pickles. it makes the soups turns spicy as i love it.
