Where to get vitamins in Atlanta area??

Hello,

I'm hoping someone might be able to help me out. I'm going to be visiting Atlanta this summer and I was wondering if anyone had found any good stores for buying bariatric friendly vitamins or foods. I'm staying downtown near the convention center, and we won't have a car as far as I know at this point :)

Also, restaurant, shopping, and sightseeing recommendations would be great too!!
