Ping Pong Dim Sum offers free food and drinks to birthday wishers

To celebrate its ten year anniversary, the dim sum restaurant chain gave away a complimentary dish and drink to any customer who performed 'Happy Birthday' to the Maitre D upon arrival.

The promotion took place last May 28, across all eight of Ping Pongs restaurants in London.

The Ping Pong dish and drink combo will include a choice of one of the most popular dishes served at Ping Pong over the last ten years, as well as a limited edition ten year anniversary cocktail.

For festive customers who shared a short clip of their performance on Twitter, Facebook or Instagram using the hashtag #PingPongSingSong, the brand will award them with a chance of getting a complimentary meal for two.

Over 100 meals have been given away.
