I am currently visiting the USA, and before I leave I want to try some food that is "uniquely" american - IE, you can't really find it outside of the country.
UK stores do tend to have a "USA section" which has a small amount of sweets and other products. But I am wondering what americans specifically missed / couldn't find in other countries.
As an example - Wendy's as far as I've seen, isn't local to the UK or at least where I live. So trying that was a "unique american food", to me.
I'm also in Chicago at the moment, so I made sure to try a proper (real?) Chicago deep dish pizza (loved it, by the way).
Alternatively, any other suggestions of food to try?
Immediate edit - turns out Wendy's is in some locations in the UK. I just assumed incorrectly!
Thanks for all the suggestions!!
There are a lot of good suggestions here and great food suggestions. Hotdogs, Italian beef sandwiches and deep dish are totally good ones. I would also suggest some fried chicken. Fried chicken is a total southern American food but thanks to the Great Migration the cuisine is common in Chicago. Anywhere with good reviews online that isn't in the rich white areas of the city will do.
