The best east Asian food in Atlanta, as your daughter has probably already been told, is along Buford Highway, from North Druid Hills (which, at its eastern end, transects the Emory campus) north to about a mile outside the perimeter (I-285). Japanese, Indian, Viet, Thai, Chinese, some of it excellent.
As Janet said, Taqueria del Sol and Fat Matt's are overrated. But if you're willing to go that far (Fat Matt's is nowhere near Emory), try
Top Flr for a nice dinner: creative food at great prices, and for some reason rarely crowded. Almost next door is
Papi's Grill for good Cuban/Caribbean sandwiches (don't know about their dinner menu). The location is a straight drive along Ponce de Leon Avenue from Emory.
And speaking of tacos, your daughter is most likely familiar with a quasi-local chain, Taco Mac (there's one in downtown Decatur). Be aware that there are TVs everywhere, but they're not obtrusively loud. Do not order tacos. Order wings, and one of the villion beers on tap or in the bottle. It's an Atlanta institution. So is
Manuel's. Good burgers and sandwiches, lots of Democratic-party and Atlanta/Georgia memorabilia -- helpful if you're missing your blue-state vibe.
