The Matilda lottery seats are generally partial view orchestra seats. The seats are fine if you have seen the show before, but I would recommend paying full price for a really good seat if it is your first time seeing it. It's such a good show... you wouldn't want to miss anything.
"The city seen from the Queensboro Bridge is always the city seen for the first time, in its first wild promise of all the mystery and the beauty in the world." - F. Scott Fitzgerald, The Great Gatsby
