We go to Hae Woon Dae, a bit outside the perimeter 5805 BuHi (Doraville). Real charcoal, not just gas burners. I find the tables in the small alcove on the side a bit too gloomy, so get one in the main room if possible.
There is one - sorry, can't remember the name - but coming from outside the perimeter, it is just inside the perimeter on the right hand side. Also like Hanwoori which is not too far, just a few exits up 285
