There's a new Yanbian restaurant on Roosevelt Avenue, just below Union Street in Flushing (136-88 Roosevelt Ave). My friend Eric M. showed it to me after a recent meal at Sol Byang Lee.
Interestingly, it appears to tie together Feng Mao & Sol Byang Lee, because the name of this place in English is Feng Mao BBQ II, while the Chinese characters are the same ones as on the awning of Sol Byang Lee.
I didn't try anything here, and they didn't have a takeout menu, but it appears to be much like Sol Byang Lee in layout, structure and food offerings.
