Korean in Little Saigon?
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.
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.
