Not sure when this opened, since nobody from my Brian in Jeollanam-do Sangmu bureau tells me anything, but it's a new addition since the last time I was in the area. A Hoa Binh (호아빈) restaurant is now in Chipyeong-dong, behind Columbus Cinema near the E-Mart in Gwangju's Sangmu area. You'll find a map here via Naver, and one on the Hoa Binh website. It's accessible via buses 지원45 지원50, and if you're going by subway you can head out exit 3 of Uncheon Station (운천역), make that right, and walk along the park until you come to, and go behind, the movie theater.
You people laugh at my enthusiasm, because Hoa Binh is hardly anything special for you Seoul or Gyeonggi folks, but Jeollanam-do has always been deprived of foreign food. This is the first Vietnamese restaurant in town since the little one near Chonnam National University closed sometime last year, and the first chain in Jeollanam-do since the Hoa Binh in Suncheon closed in April 2007. Over the past year, though, there have been some improvements. In downtown Gwangju there's now Thali, Al-Arab, and the popular First Nepal, and there's a Thai restaurant called "Thai Food" near Songjeongni Station (walk along the renovated street across from the station, and turn down the alley at the store 화이트존).
A Kraze Burger opened last year in Sangmu as well, and it serves a pretty good burger.
