At Dim Sum Icon in Hong Kong, diners are encouraged to play with their food.

Squeeze the lactating and defecating steamed dim sum bun with coconut cream inside, made to resemble one of Japan's popular Kobitos characters, and you're in for a "hilarious" experience, customers say.

But far from grossing people out, Ray Kuo, assistant manager at the restaurant, says it's one of the most popular items on the menu.
