Mountains rising out of the ocean you say?

This place is in either Cabo or Thailand somewhere? I would swear this was a property I considered staying at. Looks so familiar.
Why do you have a terrible time? You're hanging out with your friends and eating delicious food.
As for the price, I think about it as paying for novelty. Sure I know that I can just roast a chicken and it will be delicious, but you know what to expect already. And repeating it over and over will only diminish the experience. IMO 'fine dining' gives you the possibility of tasting something that you either weren't aware of or takes a large amount of time, technique, manpower, equipment, ingredients, etc. to produce.
I suppose that I don't enjoy the novelty. I like some innovation, but I find that at three stars, there is often a lot of technique and complexity and no soul. Is it masterful? Without a doubt it is, or at least, can be. But I'm nearly always left feeling empty. Also, it's theater, and I'm not a very big fan of theater, especially not participatory theater. Who really wants to be dragged to some "dinner murder mystery" experience, after all?
As for repeating something over and over diminishing the experience, I feel that it's very much the opposite. The more you eat something, the more you understand and appreciate it. The more you cook it, the better your technique becomes. I'm a creature of habit, and I don't get bored of things very easily, if at all. I am probably in the extreme on that spectrum, but I suspect that there are more people like me than like you
