Koreans stick together on most things in life in my experience. The resturants here are around 18.00 for a dinner sized bulgogi with ab out 8-10 side dishes. Galbi is around 25. There are no buffets here, might be one or two in Denver. I have tried several in LA Korea Town...there were super Legit!
I've been to some Korean restaurants in Toronto, Canada. They are also very good. The prices are better in America than Canada, but more than Korea.
Glad you have good Korean food there.
