It isn't just rugby fans who have reason to cheer the Sevens: the annual sporting extravaganza is also a boon to the hospitality and tourism industries at a time of the year that is otherwise normally quiet.
With thousands of free-spending rugby fans crowding bars and restaurants, the throng of visitors has been bolstered by those in town for yesterday's chief executive election.
At a restaurant in Mid-levels, near the University of Hong Kong, the locals and tourists enjoying Sunday lunch were split, with Hongkongers glued to coverage of the election while the visitors watched live rugby matches on the television.
'To be honest, I didn't know what the Sevens was until they [visitors] told me ... To me, today just means a good business day, even better than usual,' the restaurant owner said.
According to a recently released report from the Hong Kong Tourism Board, last year's Sevens brought in 21,391 overseas visitors, who spent an average of six days in the city.
On average, a Hong Kong Sevens visitor spent HK$12,873 during his or her trip on accommodation, shopping, dining, transport and other costs, the Tourism Board said in the report.
