JAtlanta has mentioned these 2 interesting neighborhoods. They seem to be right next to Midtown. What would be the main streets that pass through these areas for a quick walking tour ? I am staying right across from the Botanical Garden in Piedmont Park.
"I would also suggest that you walk through Little Five Points, a more bohemian area with lots of unique shops, as well as the Virginia Highlands, another neighborhood with cute boutiques. L5P has a great outdoor restaurant, the Brewhouse, which has excellent, inexpensive food and a huge patio perfect for people watchign. This neighborhood has people from all walks - bikers, mohawks, yuppies, everything."
