Great event!
Live music at almost every corner. Great quality too. Not just jazz... there was reggae and some other stuff too. It was quite a long stretch of Queen St. Everyone seemed to be having a great time and getting into the music
It was pretty packed, although didn't feel too uncomfortably crowded, maybe because it was such a large area. Large crowds do form around the performers though, so it is pretty difficult to see (even if you are tall), unless you are lucky to get there as SOON as the performance begins I think.
Quite a lot of food vendors. Only suggestion would be to sell alcohol (although there are a few bars on Queen) read more
