Just Green is a small deli on Lamma Island, located on Yung Shue Wan Main Road, which believe it or…read morenot is on the road from Yung Shue Wan ferry. It's beyond the turn off on to the family trail, but before you get to the temple.
It's basically one of a small chain, the other stores in Wan Chai, Soho, and Disco Bay, selling healthy whole foods, such as qinoa, fenugreek (nope, I have no idea what this is either), kettle chips, organic pasta, Quorn, and icecreams.
It's actually a reasonably priced shop, given the products are premium and imported like Quorn, and also have to come beyond "main" HK and onto an outlying island. Produce sells at a similar price to the regular shops in HK.
The best bit of this store (which is only at this store and not the HK ones) is the "pseudo" cafe at the rear. It's not a coffee shop, not by a far stretch. It is more like a small seating area where you can have snacks and drinks bought in store. They even have serve yourself teas, which is essentially a cup, a teabag and a kettle, and that you make up for yourself. Remember to make purchases before you enjoy. Beyond the seating area is a small pleasantly decorated terrace overlooking the sea.
On a hot day, I like to come for the real fruit lollies and hang out at the back of the shop. It's kinda pleasant to look at the sea, whilst in the AC eating ice lollies. Reminds me of Brighton Beach.
