Coming to my first game

My family and I are coming to Chicago for the first time in a little over a week, driving from NC. We are going to all three games of the Braves series right before the All-Star break (July 11-13). We will be in town for 5 days total and staying on the North Side a couple blocks from Wrigley. I was wondering if there is anything that I absolutely need to experience while I am there? (Also any places we should avoid?) Any festivals, shops, restaurants, beers, etc. We are all extremely excited about the trip especially myself. I am a lifelong Cubbie and this is a gift from my family for my college graduation, so basically this is my Mecca. Anyway thanks so much in advance and Go Cubs!
