Remember This? When McDonald's first opened in central Sydney (1972)

Mcdonald's opened their first store in Australia in 1971 in Yagoona. The following year, the first store in Central Sydney opened. It was at 632-634 George Street, not far from their current lodgings inside the former Plaza Theatre (from 1984).

Nine stores currently trade in the Sydney CBD, including the Ultimo Store at Railway Square, Darling Quarter and Darling Square. 

In recent years a number of stores have closed. There may be some on the list that are missing. Let me know if I have left any out (excluding ones that were relocated):

• Pitt & Park Street - Closed due to Sydney Metro construction. The building was demolished. 
• Martin Place - Closed due to Sydney Metro construction.
• The Rocks - The Rocks Centre
• Ground floor, Metropolitan Hotel (Corner of George and Bridge Street) - Closed due to "end of lease", as I recall, around a decade ago. 
• Harbourside Darling Harbour - Closed due to the current redevelopment of the site.
• Mid City Centre - This operated as a McDonald's Express outlet, I recall and closed due to redevelopment into the current centre.
• Centrepoint Sydney - Located in the food court before redevelopment into Westfield Sydney.
• Glasshouse - Operated as a McDonald's Express outlet but unable to provide a date of closure.
• Hunter Connection - This operated as a McDonald's Express outlet, I recall and closed sometime in the 2000s.
• Hoyts Cinema Centre, George Street
