What is it? A Time Out exclusive: five baskets of dim sum and unlimited bubbles for just £25 at seven Ping Pong locations. Why buy? Who doesn’t love dim sum? It's been gathering dumpling devotees for thousands of years now. Ping Pong is a London restaurant that knows a thing or two about these morsels of deliciousness – and with eight locations now open across the city, they must be doing something right. Check out the menu below – for just £25 a pop, you can tuck into a mouth-watering selection of dim sum at seven of their locations. Plus, we're throwing in bottomless bubbles! Because, well, we think you're all that... and dim sum (sorry).
