It's hard to put your finger on why this place is good but I suspect is a combination of the great noodles, decent topping and of course the soup/broth that hits just the right spot.
Be warned the soup is a bit salty and feels it has plenty lard in there but IT IS satisfying!
My only wish is for them to have continuous hours instead of the current open-close-open. It makes it impossible to visit the place between traditional lunch or dinner hours which is a shame.
