I did JFK-NRT in J in mid Feb.
J was pretty open -- lots of roomto spread out -- but that of course varies day to day.
They offered a choice of western meals (4 options -- beef, chicken, pasta, Salmon) along with a Japanese option. I had the salmon and thought it wsa pretty good. You can choose to have a rice bowl with you meal. Western meals were the standard J meals. I don't remeber Susi being offered JFK-NRT as an appetizer. It was on the return to DFW.
They had snack attack set up by the lavatories right after dinner. For a snack they offered Soba noodles or a paper box with a sandwich in it. I had 2 soba noodle dishes.
Arrival meal into NRT was a choice of cold chicken or cold Salmon. It looks liek it is the domestic cold lunch meal.
I thought the NYC crew was great -- especially to the senior mamas that I had on NRT-DFW.
