RE: Korean food in LA
I moved out of Simi several years ago, but there used to be a very good Korean BBQ in the shopping center at the corner of Sequoia and Los Angeles Ave. It's way back in the corner but I remember it was delicious.
In the valley, I believe there is one on Tampa Ave. in Northridge, just south of Parthenia. It's called Pine Tree Restaurant. It's been there for years and is quite good.
