Yes, I remember Bao’s opening and their dim sum chef coming from the SGV which I mentioned in my comments back in 2010. https://www.chowhound.com/post/bao-beverly-blvd-thumbs-partly-748247
A couple of Hunan style restaurants that once offered exceptionally good dim sum were Xiang Yuan Gourmet in Temple City and Taste Of China, in Chino. Consequently you can’t automatically dismiss the dim sum at a place that also serves bbq skewers.
We know they use simplified characters in Guandong, but no Guandong based restaurant has made their way to the Los Angeles area yet. Well, actually Fifty One Kitchen in Culver City is out of Guangzhou, but they are targeting a mixed audience of Chinese and non-Chinese diners. There are two or three Guangzhou based Chinese restaurants in San Francisco, though. So that’s why here in Los Angeles, any mixing of Cantonese food with simplified characters automatically gets thrown into the “fake Canto” designation.
