According to the website, “Oc” is the Vietnamese word for snail, and all types - freshwater and salt, big and small - are fried and eaten here on a daily basis.

“The preparation varies with the species of snail. Some are pan-fried with chilli, lemongrass and garlic. Others are simmered in a salty broth. Others still are grilled over coals.”

Bun rieu cua is described as a southern Vietnamese food at its finest: a fragrant soup based on crushed freshwater crabs, poured over vermicelli noodles, roast tomatoes, crab meat and simmered pork, and topped with fresh herbs, chopped banana flower and bean sprouts, garnished with shrimp paste and a spritz of lime juice.

Each bowl of "Bun rieu cua" is priced USD1.5 which is unfairly inexpensive, said Traveler.

Hoi An banh my is always “hot” among foreign tourists. This food is introduced as “a fresh, crunchy baguette filled with salad, pork, pate, fish sauce, mayonnaise and a gratuitous fried egg, wrapped in a piece of local newspaper.”

The late American celebrity chef Anthony Bourdain has made the place famous during his No Reservations TV series.

Other dishes that made the list are Dimsum (Singapore), steak (Sydney), seafood in Ibiza (Spain), crumpet (Sydney), and honey-roasted duck breast (New Zealand)./.
