The High Noon is one of my favorite venues in town. First and foremost: consistently good sound. The sound guys move around the room to make sure it sounds good everywhere. Bless you, sound guys!
There's plenty of space to get up close and personal at shows, but also plenty of options to still see from farther back with the upstairs balcony. When it's busy, the High Noon opens up bars on each side of the room, making for minimal crowd navigation to get a drink. The stage-right bar also serves pizza while it lasts if you're hungry but don't want to pop over to a neighboring establishment.
Don't miss their free summer patio shows, 2-for-1 happy hour, and the non-music events they host, too (Nerd Nite, craft fairs, Gomeroke, etc).
