Halong Day Trip & Its Famous Squid Patties

Why squid patties are Halong’s signature street food

Squid patties or cha muc Halong are made from freshly caught squid, finely minced and hand-pounded until springy. They’re then fried until golden and served with sticky rice, banh cuon (steamed rice rolls) or dipped in chili fish sauce.

Locals take pride in their squid patties, with many claiming that Halong’s version is the best in Vietnam. The chewy texture and smoky flavor come from squid caught in the bay’s cool waters.

Where travelers usually enjoy them

On a Halong day trip, visitors often encounter squid patties in:

Bustling food markets near Bai Chay and Hon Gai.
Street stalls lining Halong streets.
Cruise tours, where onboard chefs prepare them fresh.

The cultural experience of tasting squid patties

Beyond taste, squid patties embody Halong’s food culture. Sharing a plate of golden patties while cruising past limestone cliffs connects travelers to the local way of life. For many, it’s as memorable as exploring Sung Sot Cave or riding the Queen Cable Car.

Who Should Avoid Eating Squid Patties on a Halong Day Trip

While most travelers can safely enjoy squid patties, some groups should be cautious:

People with seafood allergies

If you’re allergic to seafood, squid patties are a clear no-go. Even small traces of squid protein can trigger reactions, from mild rashes to severe anaphylaxis. Since Halong kitchens often prepare squid alongside shrimp, fish and clams, cross-contamination is also a risk.

Travelers with sensitive stomachs or digestive issues

Street food in Halong is delicious but may be oily or spiced differently than what your stomach is used to. If you often get food poisoning or digestive discomfort while traveling, it might be safer to skip fried squid patties and opt for steamed seafood instead.

Pregnant women and elderly travelers

Pregnant women are advised to limit seafood intake, particularly shellfish and squid, due to mercury and bacteria risks. Elderly travelers, too, may find squid patties heavy or difficult to digest. A Halong day trip is already packed with sightseeing, so avoiding foods that could upset digestion ensures a smoother experience.

Those on strict diets

Vegetarians, vegans or those observing halal/kosher restrictions won’t find squid patties suitable. Luckily, Halong offers plenty of alternative dishes that fit these diets.

Reputable restaurants: Look for busy, clean eateries with good online reviews.
Local recommendations: Ask your tour guide where they would eat.

Pairing squid patties wisely
