When I was doing a 6-week summer program at Northwestern, summer before my senior year in high school, I stayed in a campus dorm with an assigned roommate. He was a Chicago native, and we became friends, so a couple of times per week his dad would swing by and spring us loose for lunch. They saw it as their mission to enlighten me with respect to Chicago cuisine (and believe me I was all for it, especially compared to dorm food!).
We went out and got red hots, deep dish pizza, and then one day they took me to a Greek place. I'd had Greek food before, and knew I'd like it, but for some reason I'd never had dessert at any Greek restaurant. They ordered some baklava and it looked a little weird to me, but I've always been willing to try pretty much anything. From the moment I bit into it, I knew I'd found ambrosia from the gods, and I knew it would be my favorite dessert for the rest of my life.
I don't eat it much, I don't eat any sweets all that often, but sometimes I'll go out of my way to stop by my favorite Greek place in town to snag some baklava. And it tastes as delicious today as it did back then.
