Among the places offering chocolate drinks nearby this is still my favorite - adequately thick with a dash of salt which gives it another dimension. It tastes just nice to be drank by itself and can also be slightly diluted with milk.
You can return the bottle (give it a thorough wash beforehand pls) if you feel so eco-unfriendly indulging in so many takeaway containers nowadays (no monetary incentives for that, saving the earth is the incentive) and they will sterilise and reuse it.

In frame: Sea Salt Chocolate [$7.4 walk-in, but I think $6.9 delivered with further discounts for bundles]. They are still delivering from their sister outlets, Curious Palette and Wakey Wakey.
