Christopher Schwarzenegger: I Feel 'Excellent'!

Just 2 days after he was released from the hospital following a disastrous boogie boarding accident -- Christopher Schwarzenegger walked around L.A. with a big smile on his face ... claiming he's doing "excellent!"

Chris and his big sister Katherine stepped out yesterday for a quick lunch -- and based on the sleek Mercedes SUV, the bumpy ride is over.
