My own city in the last 10 years. Amsterdam really took a nosedive. Lots of unique little shops disappeared in favor of approx. 10 million frozen yogurt/chocolate waffle stores. Tourists used to be a few chill, cheery groups interested in the city they were in - now they sometimes look like hordes of zombies hobbling from one tourist trap to the other. Painstakingly slowly, and of course taking up the whole sidewalk.
