Keiji Kida glows with satisfaction whenever a customer savors his Japanese-style gelato.

"Thank you very much," the 35-year-old entrepreneur beams while seeing his customers out of his ice-cream store in Wan Chai, a bustling commercial and residential district here.

"People in Hong Kong like the flavors of tofu, green tea, curry and rice, pumpkin and sweet potato," Kida told Kyodo News.

Despite the fact that it originated in Japan, curry-flavored ice cream is not so popular there, according to Kida.
