Whether its the Blackhawks or Bulls, the games are so much fun to go to! Chicago fans super supportive no matter how bad the teams are (most of them are Cubs fans).
I've only sat in the 300 level, never any closer and have had great seats for every game. The views that they show on WGN when the games are televised make it look like you're so high up but the second level is tiny.
My boyfriend and I sat in the 306 section (middle) and it was awesome - we were right behind the Bulls bench and could still make out all of the players from our seats. The 300s are a great way to see the Bulls in person for less money.
