What food should I eat in Phu Yen?
Five dishes define Phu Yen's food: goi ca ngu dai duong (raw yellowfin tuna, best at Dong Tac pier), goi ca mai (small fish cured in lime), bun sua (jellyfish noodle soup, market only before 8am), hau O Loan (oysters from the brackish lagoon), and cua huynh de (flat red crab, December–May only, 1,150,000–1,200,000 VND/kg). All are specific to this coast and unavailable or inferior elsewhere.
Phu Yen’s food identity comes from the sea and the specific character of this part of the Central Coast. The dishes here are different from what you’ll find in Nha Trang (resort city, international menu pressure) or Hoi An (ancient town, heritage food for tourists). They’re what a fishing family eats.
The five dishes to know
1. Goi ca ngu dai duong (Raw tuna)
Tuy Hoa is Vietnam’s largest yellowfin tuna port. The boats go out for weeks into the South China Sea and return to Dong Tac wharf. Within hours of docking, the fish appears as goi — thinly sliced, dressed with lime, fish sauce, fresh herbs, sliced onion, and toasted sesame.
This is sashimi in structure, Vietnamese in flavor. The fish at pier-side restaurants in the morning is as fresh as tuna gets outside Japan. Go to the Dong Tac pier area, not a hotel restaurant.
Cost: 80,000–150,000 VND per serving.
2. Goi ca mai (Cured fish salad)
Ca mai are small, translucent fish caught in brackish coastal waters. They’re cured in lime or vinegar (the acid “cooks” the protein, like ceviche), then tossed with fresh herbs, onion, chili, and peanuts. Eaten with sesame rice crackers or rice.
The flavor is clean and herbal — nothing like the intensity of cured sardines. Best at market stalls near Dong Tac pier, before noon.
Cost: 50,000–80,000 VND.
3. Bun sua (Jellyfish noodle soup)
Fresh jellyfish from Phu Yen’s coastal waters — firm, slightly gelatinous, clean ocean flavor — in clear, light broth with rice vermicelli. A morning dish, gone from market stalls by 8am. Find it at Cho Tuy Hoa market from 5:30am.
Cost: 25,000–40,000 VND per bowl.
4. Hau O Loan (O Loan oysters)
Oysters grown in Dam O Loan, a brackish lagoon 22km north of Tuy Hoa. The lagoon water — part fresh, part salt — concentrates minerals in the meat. The oysters are small but intensely flavored.
Best eaten on floating restaurant platforms over the lagoon itself — 50,000–100,000 VND boat ferry from shore. Raw with lime, or grilled with scallion oil.
Cost: 100,000–200,000 VND/kg fresh; 30,000–50,000 VND each grilled. Peak season: October to March.
5. Cua huynh de (Red frog crab)
A flat, bright-red crab unique to the clean-water coastal areas of Phu Yen and Khanh Hoa. Nothing like a standard crab — the shell is vivid orange-red even before cooking, the legs are paddle-shaped, and the meat is sweeter and more delicate than most crabs.
Available December to May only. Outside this window, skip it — restaurants serve frozen. Best preparation: steamed with beer and lemongrass.
Cost: 1,150,000–1,200,000 VND/kg standard size (500,000–600,000 VND/kg for mini).
Street food and market
Cho Tuy Hoa market (5:30–9am): Bun sua, banh canh he (thick noodle soup with chives), bun ca (fish noodle soup). The cheapest, most local eating in the city.
Tran Hung Dao street (evening): Grilled seafood, oc nhay (jumping snails, 100,000–200,000 VND/plate), cold beer.
