What does it mean when in Europe, a guy says you look interesting?

I am a Latina girl in Sweden. A Swedish guy randomly approached me and told me I look interesting and he wanted my number and wanted me to get drinks with him. And no I do not have any deformities or abnormalities lol. I feel like saying someone looks interesting is an insult and I was taken aback by that comment. Maybe because I am a Latina surrounded by very white blonde people, he said that? Does it have a different meaning in Europe?
