Read about this in The Sampan, so I thought it bore a mention here. It’s a delivery only via WeChat spot, all in Chinese, that makes green bean noodles by a couple from the province of Shanxi. Apparently they make thir own Shanxi vinegar as well. Seems like they make a few other items too.
Delivery is 2$ for orders over 20$ to Malden/Everett/Revere/Chelsea, 3$ to Allston/Boston and free for orders over $30.
Here’s the original review by Kingsley Tan in the Sampan.
