FCB talk has been way before 2010.
When was IHB founded?
Sept 2006? Zovall can confirm. The forum came after.
Long before Mainland China FCB, Irvine was already attracting buyers from Taiwan in 1980s. My parent's agent took them to see homes in Irvine in 1989. Interestingly my in-law's agent took them to see homes in Diamond Bar. Both of our parents turned down the location(s) because it was "too rural". LOL.
In those days Irvine's Taiwanese residents had many well to do parachute families, the dad dropped off mom and kids in Irvine then returned to Taiwan for work. They had big satellite dishes in the backyard to get overseas TV programming and drove to Ranch 99 in Anaheim off Euclid for groceries, though I think there was a short lived Diho supermarket by 5 & Culver (?) run by ex-employees from Diho in Artesia. Jamboree was flanked by vegetable farms and, before they built Tustin marketplace you could see Disneyland fireworks at night from there.
By the 90's Irvine could support 2 Ranch 99's, catering to the demographic the Ranch 99 food court (Culver) sold popular Taiwanese dishes like Squid/Cuttlefish soup and chicken rolls.
By 2000s, I think Mainlanders followed Taiwanese to Irvine with its pre-established ethnic Chinese population. Slowly, the older Taiwanese restaurants were replaced, Ranch 99 removed the Taiwanese dishes from its food court, and by 2007-2008 when Ay-Chung noodle opened in Irvine, the demographics had changed and they didn't last long. 85C stood as an exception because they broadened their target customer base.
Now in the 2020's, we're getting a small flood of Taiwanese restaurants and beverage shops opening across LA/OC again. I went to Hechalou in Long Beach earlier this week. J&G Fried Chicken opened in Hacienda Heights this year too.
