Shirts and shoes 😀
Normally there is no dress code; however, having said that they do usually turn the air down so it's cool in there. Also it may depend upon the event. Use common sense.
Not that I've seen...
I went to see a comedian and he was from the south. There was cowboy hats daisy dukes, long sun dresses and Jean's. So a variety of clothes was worn. Nice place for an event. Always so close to the stage.
