Thanks to JThur01 for the heads up of the opening of Wang Xing Ji, subtitled Juicy Dumpling, in San Gabriel Square. Since I never found the fish XLB at Dean Sin World (they looked at me real funny the two times I asked over there), I'm happy to have found them at Wang Xing Ji. It wasn't until my order arrived that I figured out that "Juicy Dumpling" referred to XLB (or for the benefit of our New York friends, the dreaded term "soup dumpling") as opposed to real dumplings. This would mean that the other varieties, such as vegetarian dumplings, are also XLB. As JThur01 points out, the signage also proclaims "Since 1913", so Wang Xing Ji is headquartered in the mother country, apparently in Wuxi. Street address is 140 W. Valley Bl., #211. For those keeping score, this restaurant opened at the tail end of 2011.
In other news at the same mall, the name of the Guilin rice noodle soup restaurant has changed from Eight Cafe to Grains Taste Rice Noodle. But the menu inside says Snowy Queen Rice Noodle. And the logos are all identical, so I don't know what's going on, though the food seems the same.
Finally, as an additional item to JThur01's Alhambra update, canoodle has opened up across the street from the former Gourmet Island in the spot that was previously a ramen restaurant. canoodle seems to serve a wide variety of items based on its exterior signage, including pho, ramen, pizza and pasta.
