This is located in the big two story Marukia on Artesia.
Supposedly it has won several best awards and hasn't even been open a month but the lines are starting to form.
Famous for it's soy based broth it is most likely chicken based and supposedly black bean as well.
It was quite good and a nice change of scenery from the typical fat bomb tonkotsu broths while having a little bit of complexity to it. Although I do think the broth could have been slightly less saltier and the cha-shu slices I had were basically one half fat and one half meat, no even layers so a bit guilty inducing.
The cha-shu bun is nice but a bit simplistic with lettuce, a sour sauce, and a salty sauce. Worth trying once but I probably wouldn't get it again. Definitely want to go back to try their pure chicken broth.
