Hà Okio, "Sài Gòn Cà Phê Sữa Đá". A very cute song. Cà phê, of course, is coffee; cà phê sữa đá is the preferred Vietnamese way of taking it, with ice and sweet condensed milk. It's a nostalgia song, remembering times, sometimes sunny, sometimes rainy, when you just hung out with friends, sometimes coming, sometimes going, drinking cà phê sữa đá in the parks in the city center.
