Magoos in Puck's Alley is always filled with college students. I am not sure about the one in Aiea but I'm sure if they offer the same type of beer and pizza, they will probably attract the same type of crowd.
Magoos' pizza is really of good quality and the ingredients taste very fresh. It is a about $25 for one pizza though. It's weird because their beers are dirt cheap! One pitcher for $6 or less and they offer such a variety, I was really surprised.
If you want good draft for cheap, go to Magoos!
