I've been eating at random little Lebanaese/Armenian bakeries around East Hollywood. I have had two excellent little piroshki/pirogi things so far. First is at a bakery on Hollywood Blvd., on the south side of the street, on the same block as Samnuluang but about three storefronts east. They also had a fried dough thing filled with cream, tasty. Second is at a minimart on Hilllhurst, in the same complex as the Drawing Room. These were slightly better, I think.
Other good bets for Armenian piroshki/pirogis? These are fried, and have somewhat the same texture as, say, a Chinese donut, but meaty and spicey inside. Me likes.
