My friends brought me to this place, and it's delicious. I normally go to Monta Ramen, it is still questionable if one was better than the other, i'd say it depends on what your taste buds are looking for. Sora provides spicy and flavorful broths. You can order broth bases such as Miso or Shoyu, and they have a wide selection of extra ingredients you can add. I must say, I love their gyoza! Cooked perfectly; crispy at the bottom, where it's been pan fried, and moist and juicy everywhere else.
I ordered my miso ramen with cold draft kirin. Best combo ever!
