Located in the heart of the city is Underground Atlanta. Six city blocks in the heart of downtown Atlanta have been transformed into a spirited marketplace that offers historic guided tours and features Kenny's Alley with 12 spectacular restaurants, more than 100 specialty stores, entertainment emporiums, street-cart merchants, and the newest attraction, Aero Balloon, an adventure ride that rises up to 350 feet above Atlanta's downtown streets. It was later fully restored and is now a tourist location offering a variety of shops, restaurants and activities for everyone to enjoy. The Underground is one of the most popular visitor attractions in Georgia.
