The Chua Bo De temple is about 25 minutes outside of the city near English Turn golf course. It's a typically Vietnamese Buddhist structure, filled with Chinese-style bodhisattvas (Buddhist saints), photos of and offerings to dead ancestors, and lots of red and gold in the color scheme. You don’t have to call ahead before visiting, but it may be polite to do so (plus, you can check if the temples are open).
To see where New Orleans Vietnamese work and play, you need to drive a little way out of the city proper. Although many Vietnamese refugees were Catholic, Vietnamese religion has always been pretty syncretic, and there were many Buddhists among the boat people. In New Orleans East, the Trung Tam Phat Giao Van Hanh temple suffered severe damage during Katrina but was rapidly rebuilt by its congregation.
