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

Kobe Beef in Kobe, Japan.

Best beef I ever had. Not worth it though. I didn't realize how loaded my friend was when she suggested it to me, so I ended up reserving for 4 people before checking the prices.

I did spend 700$ eating sushi one time though. That time was worth it. For any sushi lovers planning a Japan trip - Stay out of the main cities and go for the coast. The best sushi is far from Tokyo/Kyoto/Osaka.
