Fireworks erupt from the Peninsula Hotel to mark the iconic Hong Kong hotel's 85th birthday.

Hong Kong kicked up its heels on Wednesday night for one of the biggest birthday parties of the year.

With 2000 guests, the Peninsula Hotel celebrated its 85th year with a light show on its classic facade, fireworks, bands and DJs flown in from Paris and Tokyo.

There will be some sore heads this morning, with champagne and caviar served into the night.

Several levels of the hotel were turned over for the glamorous party, including the lobby, where high tea is a tradition, being transformed into a giant rose garden.

The Philippe Starck-designed Felix restaurant on the 28th floor took on the guise of a decadent nightclub.

The light show, set to specially composed music, featured the illustrations of Hong Kong artist Lee Chi Ching.

It told the story of the rise of the city and the hotel, including significant events such as the landing of Pan Am's China Clipper, the first passenger flight linking Asia and North America.

Robert Cheng, marketing manager of Hong Kong's Peninsula Hotel Group, said invites to the party were the "hottest ticket in Hong Kong".

"People had been asking me for invitations for months," he said.

But in a way, the partying has been going on all year. There have been special birthday events such as old-fashioned tea dances with a 10-piece big band, champagne brunches and tea parties for local 85-year-olds.

Wednesday night's heels up did, however, cap a big year for the hotel, which opened in 1928.

It has recently completed a $HK450 million ($A64 million) renovation of its 300 rooms with homely interiors, marble bathrooms and touch-screen technology that does everything from opening curtains to ordering room service.

In addition, the billionaire Kadoorie family that owns the hotel group is due to open its 10th property, in Paris, on August 1.

The family has also purchased hotel sites in London and Myanmar.

The 235-room Paris property, in the 16th arrondissement near Champs-Elysees and the Arc de Triomph, will have a small rooftop restaurant/bar with 360-degree views.

It will also have a fine dining Chinese restaurant, one of few in Paris.

"The building was a grand hotel at the turn of the century and we have essentially restored the facade and the historical parts," Mr Cheng said. "Then we have integrated some more contemporary design touches. It is a very Parisian hotel."

The London property will be in Belgravia, near Buckingham Palace and Hyde Park.

It's currently an ugly 1960s office block marked for demolition.

"The demolition will take about a year," Mr Cheng said. "We can't do anything too drastic [with noise and disruption] given our neighbour has quite a lot of pull."

Meanwhile, in Myanmar, the hotel group has purchased the former Burma Railway Building in Yangon.
