I wouldn´t wonder if there is a trend for longer meals. If someone pays 500 $ or so per person I would fully understand if 90 minutes are not what you expect.
I can't sit in one place for 3 hours without wanting to go for a walk a couple of times. Too bad I don't smoke or drink.
3+ hour meals in Tokyo are especially difficult because they keep their thermostats quite warm.
