No sooner than Shanghai Restaurant finishes sliding over from its space in San Gabriel Square to the adjacent space formerly occupied by Fantasy Eatery, the old Shanghai Restaurant space has been taken and the new occupant has opened for business. The new tenant is Shu Feng Yuan, a branch of the Sichuan style Shufeng Garden in Rowland Heights. As I recall, the Rowland Heights location has a table of cold dishes (pig ears etc.) up front, but there is no such arrangement here. From what I can tell, Shufeng Garden has a pretty good following, so now the west SGV can experience this too. There is still one empty restaurant spot remaining at San Gabriel Square, where the Japanese restaurant used to be.
Down the street and around the corner on San Gabriel Blvd. at the site of the departed Gourmet House (and before that, Spike's) the signage is up for Yunnan 168, though they're still in the construction phase. Given that most of the Yunnan style restaurants in the US are in the San Gabriel Valley, I'm not sure if we need another contender, but it's on its way.
And sadly, Shanghai Bamboo House on the corner of Temple City Blvd. and Las Tunas Dr. in Temple City is gone, to be replaced by a bank. This is doubly sad since this location has been occupied by a series of pretty good Chinese restaurants for over 20 years.
