We really like Buenos Aires, it is a great city with loads of things to see and do.
The architecture is an eclectic mix of European styles through the decades, where people have borrowed design inspiration and implemented the bits they like most, as a result none of the buildings are truly authentic but it makes for an interesting skyline. Buildings built around the same time can either look like classic European palaces or art deco concrete structures, depending on the whim and wealth of their owners.
We also loved the cafes, restaurants and bars. We have had some of the best steak we have ever eaten and tried Argentinian classics like Alfajores (shortbread like biscuit sandwich with Dulce de Leche in the middle and covered in chocolate).
You do need to adjust your body clock when you come here, everything in Argentina happens later than back home, going to dinner before 10pm is the equivalent of going out for the early bird special.
The city is easy to get around, the metro system is good and it is safe to walk most places even at night. We took advantage of a couple of great free walking tours and a bike tour to get to know the city better.
The downtown areas of the city hold the government buildings, banks, Cathedral (the previous home to the now Pope Francis), parks and gardens.
As you can see from Bills above description he is now very cultured but mainly fatter!
