Unif Tung-I Chinese Onion Flavor used to be one of my favorites too, but had so many in too short a time span, now I'm tired of them.
I've had trouble finding the Mr. Kon series that I had in Taiwan, the selection I've found here in the states is a bit more limited for the Mr. kon brand.
Other notables:
Nissin - Sukiyaki
Shin ramyun
indomie Mi Goreng (original flavor, the one served dry.)
and then. guess I'm lucky. I ate from three different ramen houses last wed,thur, and friday around the O.C.
edit--
@viggen: are you thinking about the Mitsuwa in Costa Mesa? They have a san-tou-ka there. I don't remember the Marukai in costa mesa having much to eat (only remember sushi boy, lollicup?, and a L&L's hawaiian bbq)...though it's been awhile since I've been there. There's also Kohryu and mentatsu nearby there, on Baker street. I have not tried mentatsu yet, and haven't tried enough of the menu at Kohryu to form an opinion.
in fountain valley: shinsen gumi for hakata ramen, and ebisu for sweet lunch combos.
