War Shu Gai
Also known as Boneless Almond Chicken. I used to get this in the mid west and Seattle Chinese restaurants. I can't seem to find any restaurant in Sacramento or San Jose that serves this dish. Anyone know where I can find War Shu Gai?
A quick google indicates that it's a preliminarily a middle of the country Americanized dish. Did you find it in the ID in Seattle or in the 'burbs? I'm not familiar with SJ restos but Sacto has great Chinese places that tend not to go the Americanized route. Maybe that's the problem. It may be one of those dishes that you learn to make at home if you can't find it. Good luck.
Thanks to Melanie's link, I was able to read descriptions of the dish, and it seems like it is rather close to the dish popular at Wakanoura in Sacramento about 35 years ago they called "Peanut Duck" which was invariably fabulous until Wakanoura sadly closed a few years ago. I wish I could be more help.
You won't wor su gai in California. Believe me, I've been looking for it for five years since I moved away from the Great Lakes region. I wish I could, I've been craving it for ages.
