WOW - that is a lot of questions, but all good ones . . . As far as parking near Wrigley - I always try to avoid it. On night/weekend games you can do the park and ride at Devry - but unfortunately that doesn’t help you. I am going up Thursday - and I like to park in China Town and take the L in. Are you staying in a downtown hotel? If so, they'll let you park early - even if it's before check in time (call to make sure, but my wife worked at a hotel downtown for years and that kind of thing was routine). Gates open at 11:20 and that is about when the Cubs will be wrapping up BP. The Reds will be after that. As far as pizza goes, Ginos is a trap – but a dang good trap. Then there’s always Uno’s (29 E Ohio) and Due’s (619 N Wabash Ave) – they really are the best! Good luck - as long as you make it to the park by first pitch your day will be great!!
