Carl's Jr was a destination and he predicted the restaurant would be extremely popular.
The American headquartered Carl's chain has come in for strong criticism for its calorific food but Ng is unconcerned.
"There's many other fast food operators on Queen St," he said.
Russel Creedy, restaurant Brands chief executive, said this week a Queen St Carl's Jr would open in October.
Chris Haynes, manager of the new Metro Bowling Lanes, said resource consents were in place.
"It's going to be a significant change to the standards of Auckland bowling centres. Some of them could do with a bit of a shakeup. It is a totally different type of design, the latest in lighting and sound and just the way of doing things will be different," he said.
The new hall would cater for 200 to 250 people at once and offer three groups of four lanes downstairs, four full lanes upstairs and four shorter lanes.
JNJ Investments bought the building, via Jones Lang LaSalle, last year at a discount to the government valuation of $57 million.
Chris Dibble, Jones Lang's associate research director, said fast food was a major magnet for consumer spending along Queen St.
"Those outlets are very conscious that Auckland's CBD provides a large customer base with approximately 90,000 people working in the city centre and 25,000 people living there," Dibble said.
"A further 60,000-plus are in tertiary education there and 12,000 tourists visit it each day.
"Luxury retail has primarily located in lower Queen St, High St and Britomart."
He said food outlets catered to varying pools of consumer tastes and requirements.
"The top of Queen St remains very popular for food outlets catering to movie and theatre goers, office workers, residents and [tertiary] students," Dibble said.
