We had the original and the shoyu. I felt the shoyu was lacking flavour a bit. The noodles were pretty good and broth was light. Actually we mixed the broth from the shoyu and the original and it tasted amazing!
The double toppings not really worth it as you get 1 extra piece of seaweed, half egg and 2 thin slices of meat for $4.
Will definitely be back, it's the best option for ramen in the area.
