From the looks of the menu: http://www.yelp.com/biz_photos/sDZjC5... , this is the 3rd (or shall I say second?) branch of Bebe Restaurant. And if that's truly the case, consider Arcadia lucky.
Bebe is as Taiwanese as they come. The kitchen is so flexible, they'll literally cook anything Taiwanese as long as they have the ingredients. That liver (or kidney, I much prefer the kidney with the white wine) soup is so very cuisine tipico of Taiwanese. Meant for the poor, enjoyed by all.
Thanks for keeping us updated on the happenings of NW. SGV.
