The Castlereagh Boutique Hotel in the heart of Sydney CBD offers eight rooms for meetings, workshops, receptions and dinners. Groups range from ten people around the boardroom table to 200 guests in the King George Room. The hotel is heritage-listed and keeps many original 1920s features, which gives corporate days and private dinners a distinct setting.

The Boardroom on level 1 seats 10 to 12 and is known for its early twentieth-century board table.
