The LM Plus restaurants in Central Park and Park Avenue not only have a half-price takeaway bottle deal but also the best lineup of Sardinian wines I have seen in Beijing, including from well-regarded producers like Cantina di Santadi and Argiolas. In fact, owner Massimo Masili works directly with Argiolas to make his house wines.
The white is made with vermentino grapes while the red is a blend of grapes locally known as Cannonau, Monica and Bovale Sardo — Cannonau goes elsewhere by the name Grenache, among others. I tried the latter at the former Upper East Side outlet with the pizza tonno and found the combo so tasty I downed a whole bottle.
The wine menu includes dozens of other options, from countries the world over, all at 50 percent off for takeaway. The only exceptions are a small number of expensive / rare wines.
You can find LM Plus at number 103 in Building 6 at Central Park and 1F of the Park Avenue Club House.
