I started backwards, I don't know why just wanted to do this in order of answers that came to mind first.
I would want to eat the most fresh and best tasting sushi platter ( at least a quarter all salmon types of sushi) of my life and have it made in front of me by Iron chef Masaharu Morimoto (if that's allowed if not then a really good sushi chef).
I would want to go to Venice (even if it's opposite country to what I chose to eat) and go on the river canals while someone plays 'Spanish romance' at perfect tempo on acoustic guitar while I'm on a gondola (complicated but if I could hey... I am a sucker for romance and feeling it)
Lastly I would want to meet Ryan Reynolds (because he's hot and I heard he's a true romantic) and have him accompany to all the above.
