Gwinnett area = Haru Ichiban (in Duluth)
or Mori House (in Suwanee)
On the way to Gwinnett, right within the loop near I-85.
look for a place called Shoya (in Doraville)
That should cover most bases.
and a plug for my friend,
If you're interested in the best Chinese food around,
check out Ming's BBQ (in Duluth) off of Pleasant Hill Rd, exit 104. (which is just around the corner from previously mentioned Haru Ichiban)
