I've only travelled to America once, Florida. One of my lasting impressions was the size of portions when eating out. You ask for an individual salad and you're given a bowl that's twice as big as a salad you might share between a table where I currently live(Spain). Maybe salad isn't the best example, but it extended to every meal I ordered, chips, meat, pasta, whatever. Whenever an order arrived the eyebrows around my table would go up, followed by some gentle laughing about how we're going to finish it all... Smaller portions would go a long way towards reducing waste. You can always order more food, but as you say, once food has been delivered on a plate it can only really go in the bin.
