Book is 36 Perspectives of Saigon [Sài Gòn 36 Góc Nhìn]. Published in Hanoi in 2005, it includes these pieces, "I Love Saigon," "Saigon Impression," "Saigon Through My Eyes," "Saigon! Saigon!" and "Saigon Alleys," etc. I know an American sexpat who spent over a year in Saigon without realizing it's how locals refer to their city.
