Hi Dan,

I used to live near Nowon Station, and my fiance and I loved this tiny broiled mackerel restaurant near the GS25.  I don't know which subway exit it is near, but there is always a long line of people waiting to be seated in the alleyway outside GS. Also, there is a bar in Hyewha called Basquiat that has a nice ambiance, and the owner's friends occasionally play jazz for patrons. Hope this helps!
