I have been to the city of Goiania for 5 days back in Jan of 2010. A friend from SF here has family back there in Goiania and invited me to stay while he was there. Thank you Tony and his sister Tania for their genuine Brazilian hospitality.
One of my beat friend's hometown, love the people there, oh , also the food is AMAZING... P.S. if you like BBQ
A nice city. I may not have that much to see in terms of tourism attractions, but it has a busy and friendly night life with lots of great pubs and restaurants.
