Great restaurants in New Malden, and H Mart is incredible if you're willing to walk 15 minutes from the station. The restaurant/ karaoke bar Han (right next to the station) was featured in Killing Eve as the restaurant that Sandra Oh's character works at in series 3.

Confirmed! It was a recent discovery of ours and have been going there more frequently. Very good quality food and goods. Makes it much more reachable than places in central London if you're based near south border of greater London
