Is it Sunnyvale or MV? It's the new Parc Hong Kong on Lawrence Express Way. It's related to the Parc HK in SF, but not exactly a branch (some shared ownership, I think).
This one, however, fails. We went for dim sum. The offering was nothing special, the usualy items. A couple of the good ones are Har Gua, fried taro. That's about it. The others are not particularly well done, items are too big (not delicate, like dim sum should be), and some had textures that are not tasty.
Last night we actually went to the Geary location for dinner. We had the lobster and crab special ($14.99 each). They were done quite well, esp. the crab with bean threads hot pot. Our experiences with this location for dim sum have always been good.
