So what are Sky Gardens? They are rooftop outdoor gardens on most large department stores. I have seen them in a Shinsegae and Lotte department store. The one I visited with Little Z was the Sky Garden at Lotte's department store. The garden was manicured and immaculately clean! There's supervisors around to ensure the garden stays spotless! After being strapped down in a pram all day, Little Z was ecstatic to be running around free at the Sky Garden. If you are looking for some outdoor fresh air, these Sky Gardens are the way to go!
