What's the most expensive thing you've eaten? Was it worth it?

I was at a restaurant in Hawaii, on the menu was surf and turf.... Wagyu and lobster from 'the least inhabited Island on the planet'.

I wasn't paying so I got it. It was spectacular. I had Wagyu again at a Gorden Ramsey restaurant in Vegas and it wasn't as good. Wagyu steak isn't a great way to consume it imo.
