If you were to add up the amount of time I spent at Murphy's in college, it would probably be close to the total time I spent in class. Even today, this haunt is still our campus favorite when down in CU for a football/basketball/hockey game.
Back in my day, they didn't have the new addition but having the additional space makes it much easier to get a table and some space to move around without affecting the divey-campus bar feel. Wednesday is Logo Glass Night, and I have several boxes of the great glasses I accumulated over the years.
Their beers on tap is great, especially for a campus bar. The food is pretty good pub grub, but I believe there is a "game-day menu" where only certain things are served, which is kind of a bummer if you want Irish nachos on game-day because it's not on the menu. The jukebox is great (every fricking song by The Black Keys can be found on there) and there are loads of flat screens to catch whatever game is on. If you get there early, you won't even have to pay a cover.
