We took some GoLite Whims to France, not just as (almost) rain pants, but also as something to wear in the evenings in hotels (a few times) when our ordinary walking trousers were muddy and smelly, and also as something to wear when we took all the rest of out clothing to the laundromat!
Me, I wouldn't take much food. Weighs a ton, and the locals MUST eat something. Probably quite well, and you WILL be able to afford to buy.
But I would look at having something like a thin flat bit of plastic (1.5 mm polyethylene) to serve as a general cutting board and food preparation plate. I will bet on some sort of bread being available - we ate LOTs, with jam and cheese. That means you should also be carrying some sort of knife which can cut bread and cheese and sausage. A plastic airline knife is all very well, but we do carry one good metal knife as well.
And a GSI plastic cup will turn out to be valuable too. Turkish coffee ... :-)
