dekalb is excellent and an institution.
If the "Atlanta"market is on Buford hwy, then yes -- if it is not I am not familiar.
less breakfat sausage than evening burger, nevertheless, this is one of the best veggie burgers out there!
a large pinch of ground chipotle helps...
dont know much about tex mex. heard good things about the food at nuevo laredo -- but also heard the prices are a bit high for the quality...
some easy and obvious choices:
Veitnamese: da loi is widely considered one of the better pho houses in ATL -- and there are 2 - one [kinda] near the airport on jonesboro and one up buford hwy.
Near Emory? -- many choices from decent to top notch, a good place to start your search is Decatur Square [discussed often here and on atlantacuisine.com]. on the other side of Emory a little gem called floataway cafe lurks down Zonolite road.
Disclaimer from a frequent marta user: limiting yourself to marta is well, limiting.
I assume you will not be riding busses [often an extremely unsatisfying experience]
A quick sampling [not exhaustive] – have fun – Atlanta is a great place to live and can be a crappy place to visit…weird but true….
EASTLINE [Indian creek]:
Eastlake station: Wahoo, 15 –20 minute walk south to Oakhurst village with many options – more hip than good but worth a visit for how intown locals tend to live/work/play.
Candler park station: radial, flying biscuit [not so good anymore but famous]; gato bizco [way underrated IMHO]; candler park market – wine and sandwiches
Inman park station;
Eastpoint Station: matilda bean [still there?] oz pizza; others
College park station: very much in flux sometime has some good stuff – not sure what is open there now
Midtown Station: Walk 5 blocks south to one of the more prominent midtown central business districts @ 10th and piedmont – very gay friendly. Coffee; sushi; Mediterranean [eh]; tapas. name it… piedmont park! Worth a walk around on a nice day.
Lenox – lenox mall food court – free samples; near the mall on peachtree – bluepointe; palm; others
