I was introduced to Vietnamese food when I was living in San Francisco. My Vietnamese friends cooked for me and took me to the Bay Area's best Vietnamese restaurants, whose unassuming exteriors gave no indication of the excellent food they were serving. My friends sincerely believed Vietnamese was one of the world's greatest cuisines, and I agree.
Because the Vietnamese make liberal use of fresh herbs and raw vegetables, the food tastes especially good when the weather is hot and humid. Although Vietnamese restaurants in Hong Kong are often stingy, the selection on the fresh herb and raw vegetable platters served in Vietnam is astonishing, even at the dingiest noodle shops.
If you're cooking for a group, take a trip to the shops of Wan Chai, around Stone Nullah Lane - it's much cheaper than shopping at a supermarket. These shops sell bags of fresh herbs, chillies, limes, rice papers and fine rice vermicelli. If you travel to Vietnam, you'll find the rice papers are different from the kind you buy here: they're thinner and more pliable and don't need to be soaked in water before rolling them.
