Korean in Little Saigon?
I have yet to really start exploring the Korean scene down there -- my wife was not into Korean food while pregnant and it's hard to go out for long times with a baby -- but stay away from Korea House on Brookhurst, it is low-quality AYCE food.
There's also a huge Korean community in Buena Park, which isn't that far away from Garden Grove... drive up Beach Blvd. and revel in the hangul.
They should know that GG is the Koreatown of OC. it's the 2nd largest concentration of Korean businesses 2nd only to K-town in LA. so there are a ton of places, some that are better than those in LA. Apparently the area has been branded "Little Seoul". whatever.
My favorite is Hangari Kalgooksu. GG also has a branch of BCD and a bunch of other K-town places.
