Relax...people read a lot here. I've never flown NH First, let alone SPECIFICALLY from ORD. It's Asian First, it's probably great. Your best bet is going to be looking up a review online based on the aircraft not the originating airport as that has little bearing on it.
NH J on the 777 square style seating was great, very comfortable, huge table tray, great service as is customary on ANA. I didn't like their selection of liquor, but I was on a morning flight so maybe it's different long haul. They only had whisky, beer and I think wine on the GMP-HND flight I was on.
