To weigh in on food (I forgot to do so when I read that convo a while ago): for what it's worth, @MRJ, I somewhat agree with you that the Internet (or review sites/apps at least) is not the best way to find good restaurants in the US. Most of the really good restaurants I've been to in the States I've learned about through friends, family, or just general word-of-mouth. Some places develop enough of a reputation that they end up being mentioned on multiple travel blogs and food articles too, which I find infinitely more helpful than review sites.
That being said, I also agree that American restaurants almost universally serve too large of portions (although I make use of that by taking it home and getting two meals for the price of one
) and I can see how our fast food and casual food chains would seem unappetizing to foreigners. Unfortunately, most zoo food in the US is similar to what you'd find at chains, in both food type and quality... but more expensive, since it's a revenue source for the zoo. Personally, I like to eat cheaper and healthier, so I normally bring food into the zoo rather than buying it there.
