Best music venue in Madison without a doubt. No one else even compares. Great setup, excellent staff, and cheap drinks to boot! Even during shows! And the talent that is brought in is wonderfully varied. Country, bluegrass, indie, occasional hip hop, stoner rock, metal, songwriters, reggae, Gomeroke. You name the genre and the High Noon will probably have a show for you that week.
I was just there for a sold out show a couple weeks ago and the place never felt claustrophobic. There's plenty of room to mill about and enjoy the show in your own way and still be able to pretty easily see the stage. The only downside I saw was the doors not opening until immediately before the first band started. I was hoping to get a few more PBRs in me before then.
