Enjoy your flight!
Mmmm. I'm more interested in the katsu sandwich and suntory beer! What a combination of Japanese comfort foods!
I second Rusty's response. Japanese curry is pretty easy to make and I wouldn't make it a culinary must, especially in F class. Try the other items first, if you're in London there is a CoCo Ichibanya that has opened which you can try in case you miss it in Japan which is very good in curry standards. Cheers!
