In addition to Bund and Z&Y which now sports lines like Golden Gate Bakery in SF Chinatown at times, there are the following non Cantonese Chinese in the area
House of Xian Dumpling (near House of Nanking)

Don’t think so. I’d say it’s more widespread Cantonese with a ton of variations. Sometime in the last 2 years there was a small fad in Hong Kong where one restaurant offered a super pricey rendition of steamed pork patty with razor clams (Scotland or Ireland)…a waste basically of fresh imported seafood.
The “country bumpkin” style renditions (whether home or cooked by Toishanese chefs) are likely to be more rustic in flavor and arguably a bit less refined in the preparations (the minced pork not chopped as fine [double cleaver technique] and/or hand mixed/tossed in the bowl to create that needed texture).
Great pix, brought me back to my childhood, when no Chinese restaurant would serve this rural dish largely because of its foreign smell. Now, while not common, it and its accompaniment, salted fish, can be found in many Canto restaurants, particularly in fried rice.
embassy kitchen offers 2 variants in their lunch special menu. they’re both pretty good. as a matter of fact we ordered BOTH for the same meal because we liked them so much.
and 20 years ago, wing hing deli at the corner of third & valley in alhambra would make one with chinese sausage if you asked but it wasn’t on the menu. i went there about once a week back then and would polish off massive amounts of rice with one of those.
