With a long-standing vegetarian practice of Buddhism tradition and increasing attention towards health and environment, there are more and more Vietnamese people converting to vegans and this becomes a popular consumption trend in Vietnam. For a better understanding of the vegetarian's conception and consumption habits and behavior of consumers, a survey has been carried out on 334 people randomly selected in Ho Chi Minh city. The results showed that the proportion of vegetarians (50.3 percent) and of the people who are interested in vegetarian (68 percent) is relatively high. This demonstrates the growing demand for vegetarian. The motivation as well as the barriers of practicing vegetarian has been explored. The consumption of vegetarian dishes has also been discussed. Positive thinking about vegetarian dishes has been reported, for example: 74 percent of people agreed that a vegetarian diet ensures nutrition intake, 58 percent of people agreed that vegetarian restaurants have good practice for food hygiene and safety. Three criteria for selecting a vegetarian restaurant have been pointed out: good tasting dishes, clean and reasonable price.
