LOL - Here in Illinois we just "Americanize" foreign names. Chicago has a Goethe St (should be pronounced like the German author it was named for- kind of like Ger-teh) and instead it is pronounced Go-thee. The city of Cairo, IL one would thing would be pronounced the same as the city in Egypt - Nope, it is Kay-ro - hard accent on the Kay. A road near me is Schmale Rd. Oldtime locals call it Shmah-Leh (german pronounciation) because they knew the original family it was named for. As the suburbs expanded and population exploded, it is now pronounced Sh-Male (like telling a male person to be quiet! LOL) I even hear this on the local traffic reports.
I've never heard a Chicagoan pronounce Pommes Frites, but I bet it would be Pahm-mehs Frights!
