Reserving is better, but you can buy tickets in the lobby area if there are still seats available. It was absolutely packed on a Thursday evening when we went, though, so buying ahead is definitely best.
It's best to go to the very first show of the day and you should be able to get good seats.
Make sure u get there 45 minutes early they start serving the food then
Day of is good. Weekends can sell out quick depending on size of party.
