Green Grotto- What a find in downtown LA! Green Grotto is small spot on Spring st that offers organic juices, smoothies and acai bowls. I got the Green Juice , which was great but the star was the acai bowl. These guys do it right. Definitely an inspiring Acai Bowl. This spot is in a tiny mall area in between 2 blocks. You can easily miss it (I did!) I played tennis at the YMCA and worked out so I was ready for some plantpowered nourishment and Green Grotto juice bar did the trick in a major way!
