Oooh... That's a tough one. I love food so much! I could easily answer a dozen different things for different reasons. Not only the taste itself, but also the mood, circumstances and emotions associated with it play a role in my final anser:
A bowl of Ramen from a "hole in the wall" in New York's Chinatown.
Wait. The question is supposed to be answered in 1 word lol.
A: Ramen!
Q: what/how/where would a perfect day end for you?
