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

Some dinner at a fancy restaurant my fiance took me to for my birthday. I did my best to be respectful but I hated everything about it. The food tasted no better than a cheaper restaurant and everyone was so insanely pretentious. Would never choose something like that on my own. All the people with money I know love the place, but I would honestly be happier going to an Applebee's than throwing my money into the garbage like that and have to have stuffy unrelatable conversations with strangers.
