Looks like I will be going to the July 2nd show if I get tickets hopefully. I gave up on U2 coming back to Ohio, they have not been here since their "Elevation" tour in 2001. I saw that there is a tavern nearby United Center that lets you park for free, and has a shuttle that takes you to United Center. As far as where to eat, this will be a first time to Chicago for me, so I don't know the best places, but I hear there is a Diner near United Center that is really good. Sorry, can't recall the name of the tavern, or the diner.
