I have very fond memories of being offered cup noodles on BR, I believe in economy, PE and Biz through the years. I think these days they offer a branded option served in a bowl though, similar to ANA's Ippudo offering. To this day I will bring a couple Shin ramens (the type that comes in its own cup) on longer trips to Europe or ANZ, though good Asian food is available in more and more places around the world. Really makes me appreciate the breadth of quality food in NYC/SF/LA, really not many other places like it outside the US (can't think of anywhere other than London).
