No more Old/New Scenic, Stub, Bridge, Lakeshore, Bypass, Outer/Inner Circular, North-south, Air Force Scenic taxiways anymore.....
That's been gone for a while as far as I know.
ORD has always been a mess. If you're operating in and out of there with regularity, it's manageable. But if you're only there every once in a while, it's a bear.
ORD, at least to me, has always been like walking in a hyper busy "locals only" restaurant without a menu and you only have a short time for lunch. The patrons are very fast to mock you for unfamiliarity and all you want to do is key your mic and say "Shut your asses, I'm here like once every 18 months. This isn't the center of the world. Can a brother get a damn quesadilla? Oh, when your editorial comments are over, I see you call it a cheese crisp here, whatever."
The controllers are good for the cluster that is the airport design, have a strange penchant for putting you in non-stabilized situations and asking for some things that your airplane isn't quite capable of. Some of the regular pilots can get a little "heady" and macho. ("Huh, SouthernJets rolled out to (taxiway)" and your parenthetical thought bubble reads: "Mind your business, son, ER's don't like to 'dip below VASI' and 'jam on the brakes and noisemakers' to look cool for everyone holding short")
Man, I gotta eat. Hungry.
