Hi board. I performed a search and found a place that sounded interesting in Sunnyvale only to see the last post by M. Wong stating that the place had closed... :-(
For the record, I have not enjoyed anything at Yulong off Castro.
I read all the links and it seem like Zha Jiang Noodles are a "comfort food." That sounds great. I have only enjoyed the pork version. Wikedpedia had a photo with thick white noodles. I have always had it with the thicker (egg?) noodles.
Thanks for recommendations - anwhere from Palo Alto down to Santa Clara is fine.
