Beer drinking prevails as a favorite pastime. Australian beers are very strong, and Aussies love them as a result. Foster's is probably the most famous, but most locals prefer Toohey's and Victoria Bitter. It is customary for people to take turns buying the group drinks while out. This is known as a shout.
Cocktails are also popular, but very expensive outside of happy hours.
Again, the Kings Cross area is a good place to head out for nightlife. Many pubs now contain annoying poker machines, so you may have to search a bit to find a quieter atmosphere. The club scene is hopping between Kings Cross and Oxford. Clubs tend to be rather snobby and have a steep cover charge, but the party goes until the early hours of the morning. Sports, particularly cricket, are very popular.
