Didn't get much brotherly love when i was there, less than friendly people. But had a ball with the museums. They had an exhibit on renaud back then. Lost myself there, didn't even complete. The rodin museum is nearby too. Spent an afternoon sketching forms with other art students lol
Pizza was good at the italian quarter
