I'd hope I know the area well... I lived in Summerville for 6 months in 2000 (moved with the girl I was dating at the time) and worked at that Best Buy (517!!), so, I got familiar with that whole area.
The Old Country Buffet... blecch. I'm not a big buffet fan.
Although, not to backpedal too far, but, the chinese buffet over by the Navy Credit Union isn't too bad.
