This is the best juice shop I have found in Guting. I personally really love the watermelon juice as I think it is the most refreshing I have had from there. It is quite busy for a juice shop it seems very popular and well known. Below is a picture of the shop.
It is on Tong An Street, close to where the street crosses with Tingzhou Road. There is an 85c opposite it on the other side of road. If your in Guting or live in this area, I highly, highly recommend the watermelon juice boy is it good!
