The Perth CBD's newest retail offering will throw open its doors on September 17.

The new Raine Square development will open next week.

Stage one of the $200 million Raine Square redevelopment, anchored by a new nine-screen cinema complex, a Michelin-starred dim sum chain restaurant and a Coles, had been in the planning pipeline for more than four years and took 12 months to complete.

It will also feature 12 casual dining restaurants and a range of specialty stores.

The redevelopment forced the closure of popular after-work watering hole The Moon and Sixpence, which will be replaced by 12 casual dining restaurants and a range of new specialty stores.
