Hong Kong’s party district Lan Kwai Fong could see a 20 to 25 per cent jump in business this Halloween compared with last year, according to a nightlife tycoon, who cited a “crazy” week-long build-up of costumed revellers and “fully booked” venues.

Lan Kwai Fong Group chairman Allan Zeman, also dubbed the father of the nightlife district in Central, joined in the festivities leading up to Halloween by cosplaying as the character Wednesday from the Addams Family while walking on a red carpet in a public appearance earlier this month to help promote tourism in the city.

With so many revellers expected to crowd the streets at Lan Kwai Fong, police imposed special traffic arrangements by closing roads in the area from 2pm in D’Aguilar Street between Wyndham Street and Wellington Street, Lan Kwai Fong, Wing Wah Lane, Wo On Lane, Wellington Street between Wyndham Street and D’Aguilar Street and On Lan Street.

Police warned that more roads in the area could be sealed off depending on the crowd situation.

Zeman said on Friday his forecast was based on business being “much, much better” in recent months and the festival falling on a Friday.

“I’m looking at anywhere from 20 per cent, 25 per cent above last year. Lan Kwai Fong has been crazy with many, many people dressed up in different costumes … all week. So there’s a momentum building for tonight,” he said.

“We have a lot of pre-bookings. A lot of the bars and restaurants have been booked, fully booked, actually.
