The General Post Office building on Martin Place in the CBD is one of the most historic and celebrated buildings in Sydney. It has stood on its spot since 1874, and is considered a classic of the Italian Renaissance style of architecture. The inside is just as spectacular as the facade, with plenty of restaurants to enthrall the dining public of Sydney. Those with a taste for Spanish cuisine will head straight to Postales Restaurante & Tapas Bar, where they offer up a huge range of Iberian favourites and small plate delicacies. Their tapas selection has been described as the best in Australia, and their wine list is packed with vintages from all over the old country, so you really have no excuse not to make your way down and sample their whole selection of Spanish specialities. Book ahead though, as they have been known to get very busy.
