I would second Haru Ichiban for ramen. Most of their menu is quite good, reasonably priced for the quality, and the setting is nice, too. Their sushi is excellent.
As for pho, I would send you to Pho Dai Loi on Buford Hwy. Pho Hoa changed hands awhile back and isn't any good anymore. A Vietnamese co-worker took me to Pho Dai Loi and I have never looked back.
Crap, now I'm hungry.
