If the cost per hour to say, go to the movies has tripled, but attendance has gone down by half, then by cost, more movie entertainment is being consumed than ever before, but the number of people and number of hours participating in the activity has actually gone down
The best data I could find shows a decline of around 25% from 2006 to 2023 in restaurant visits. However, a big portion of this is because of meal delivery which is more expensive than restaurants, so the cause is probably not mostly increased cost.
Other related things like concert attendance have gone up.
My take is that the main reason young people don't go out is not price, they often seem to be making choices that cost more when they avoid going out
