hanged moss plant balls

Yesterday evening, while we were entering the restaurant I didn't notice these hanged plants at the entrance of the restaurant. Most probably the reason was to focused on what to eat  :)

After we had delicious dinner and nice time, we noticed them on the way back. First I thought they were plastic but when I looked closer, it was obvious that they are real. I really like the idea. After small search on google I learned these hanged plants called as "Moss plant balls"

by the way the restaurant (Saladicious  )  has great ambiance & decoration with delicious dishes.
