Unfortunately it appears that Atlanta currently has the Pacific NW’s weather patterns. We are all ready for this gloomy, rainy weather to end.
The aquarium is a great place to spend time. The Martin Luther King Jr. Center can be an enlightening experience, as is the Carter Center, but both are harder to get to without your own transportation.
Visiting the Varsity Restaurant is a rite of passage downtown, not too far from Georgia Tech campus. Greasy food, loud and crowded, and every politician makes sure to stop there to shake hands and get their picture made. Frosted orange shakes are famous. Also, Atlanta is the home of Chickfila, if she has never had the chance to eat their chicken sandwich.
Atlanta is not set up to be a good walking downtown, and of course there are streets you need to avoid for safety reasons. There are pockets of areas that are walkable and enjoyable to visit with great restaurants and unique shops. You just can’t get to them without transportation, and honestly I would not be thrilled with having my D walk to get to some of those neighborhoods by herself.
