The United Centre is an office building which is being used as a super swanky stand in for the Hong Kong Police Headquarters. Great view along Queensway of (from left to right) the High Court, Bank of China Tower, HSBC Headquarters Building, Bank of China Building and the Lippo Centre Towers.
There doesn't seem to be a way to get to the main entrance using Street View, but the shot where Kent Cheng is taking a call on the balcony area and the shot from the start of the film where Law Kar-Ying is asking for police protection.
