Went to the Franklin Institute in Philadelphia today - very impressive science museum.  And then to the Fogo de Chao churrascuria for a late lunch.  So much for my going vegetarian! They did have some delicious picanha.  It was very busy but it was funny how after we had finally managed to meet a couple of Brazilian waiters and introduced ourselves, we received top-clas service with a smaile - and loads more picanha!
