Hollywood was a shocker to me. Very dangerous - there was even an armed guard at Burger King.
Paris - dirty, over priced and the locals were miserable.
Disneyland Paris - really, really run down in the early 2000's.
TGI's and Hardrock Cafe's all seem to look a bit run down these days.
Chicago Airport - bizarrely small Terminal for International flights. Only ONE proper restaurant where you could get a beer and a burger, and it was tiny, hence the enormous queue to get in. If you didn't eat there, you were stuck with fast food. Only a handful of shops as well. It's probably the worst airport I've ever been in, and I've been in a lot!
