A lot of it is hand-food, yeah, which I'd never thought about but it makes sense. Most of the dishes are also made of some sort of plastic-composite instead of ceramic or metal, which probably helps. In either case I haven't really noticed the noise; I'm more likely to notice someone loudly chomping popcorn a couple seats over than forks clanging on dishes, which, what can you do. Another thing that helps is almost nobody orders boxed candy because you can get much better desserts, so you never hear M&M's and such rattling around. Glasses are also open-top, so there's no straw squeaking either.
