This is about the San Francisco Oh-Toro. I don't know how long this chain has been operating here in PC but it really fulfills a need for me. Although the broth of the Tonkotsu was satisfying, I miss the deep deep flavors of the long simmered bone broth I am used to. Also I need fresh pickled ginger shaved over my dish and some hot peppers. Also I had some kind of bacalado croquette but catering to a Panamanian sweet tooth the appetizer was really rich, but I got used to it. All in all this is exactly the kind of noodle house I've been craving here in Panama City.
