In London, there is a new bar called Bunga 90 themed on nostalgia, with an entrance through a mock-up Blockbuster-esque video store and bands like The Cranberries blasting over the loudspeakers.
Nostalgia for the 1990s is not new. Experts say that 20 years is the general threshold for trends to cycle back, with two decades being the amount of time required to start feeling wistful about another era rather than seeing it as the recent past. Think about how the Americana musical Grease was released in 1978, but set in 1958.
