A pot of simmering broth in the center of the table, a pile of raw ingredients beside it, and a group of people who aren't in a hurry — that's "lau" in its simplest form. But spend any time eating across Vietnam (베트남 / 越南 / ベトナム) and you'll realize how much variation hides behind that single word.
What Lau Actually Is
Lau is Vietnam's hotpot tradition: a communal cooking format where a single pot of seasoned broth sits over a flame or induction burner at the table, and diners drop in raw vegetables, meat, seafood, noodles, and tofu as they go. The concept isn't uniquely Vietnamese — neighboring countries have their own versions — but Vietnam has developed a set of distinct regional styles that don't borrow much from anyone else.
The word "lau" simply means hotpot or fondue in Vietnamese. It appears on menus everywhere from Hanoi's Old Quarter to Saigon's back-alley restaurants to roadside stalls in the Mekong Delta (메콩 델타 / 湄公河三角洲 / メコンデルタ). The format is consistent; the broths and proteins are where things get interesting.
Lau is almost always an evening meal. It's slow by design — not something you order alone in 20 minutes. Groups of four or more are the norm, which is why most lau spots are priced per table or per person (expect 150,000–400,000 VND per person depending on the protein and location).
The Broth Is the Whole Point
Unlike some hotpot traditions where the broth is a neutral base, Vietnamese lau broths are often complex starting points — heavily seasoned before the first ingredient hits the pot. They're grouped loosely into clear (nuoc leo) and cloudy or fermented styles.
Lau Mam — The Mekong's Fermented Masterpiece
"Lau mam" is the most Southern and arguably the most polarizing variant. The base is built from "mam ca loc" or "mam ca sac" — fermented snakehead fish paste — cooked down into a pungent, deeply savory broth. It's then loaded with pork belly, shrimp, squid, eggplant, and an enormous pile of fresh herbs: water lily stems, banana blossom, morning glory, bean sprouts. The smell hits you before the bowl does.
This is the hotpot of the Mekong Delta. In Can Tho and the surrounding provinces, it's weekend family food. In Saigon (사이공 / 西贡 / サイゴン), it has a strong following in the District 4 and District 8 restaurant strips, where Mekong-origin families have kept the tradition going.
Lau De — Goat Hotpot on the Central Coast
"Lau de" is concentrated in Ninh Binh (닌빈 / 宁平 / ニンビン) and the provinces running south toward Da Nang. Goat meat — often marinated in lemongrass and galangal — goes into a clear or lightly spiced broth alongside goat offal and river greens. It's paired with rice paper for wrapping and dipped in a fermented shrimp paste called "mam tom" thinned with lime.
Goat is a lean, slightly gamey protein that works well in the long-simmering hotpot format. The cleaner broth lets the meat carry the flavor. In Ninh Binh, lau de restaurants cluster near the limestone karst areas and do strong business with both locals and tourists who've spent the day on the water at Tam Coc.
Lau Ca Keo — Mudskipper Hotpot from the South
"Lau ca keo" (mudskipper hotpot) is hyper-regional, built around a small fish that lives in tidal mud flats along the Southern coast. The fish are cooked in a tamarind-soured broth with tomato, pineapple, and rice paddy herb. The flavor is sharp, bright, and slightly funky. Outside of the Mekong Delta and coastal Ca Mau province, it's nearly impossible to find.
Lau Thai — The Import That Stayed
"Lau Thai" — loosely modeled on Thai-style sour and spicy broth — is technically not indigenous, but it's been adapted into Vietnam's restaurant scene so thoroughly over the past 20 years that it now has its own Vietnamese character. The broth is sour from tamarind and lime, hot from fresh chilies, and fragrant with lemongrass and kaffir lime leaf. Seafood is the standard protein: clams, shrimp, squid, fish fillet.
Lau Thai is now one of the most common hotpot formats in urban Vietnam, particularly in Saigon and Da Nang (다낭 / 岘港 / ダナン). It's approachable for newcomers because the sourness and heat are upfront and legible — there's no fermented funk to negotiate.
Northern Styles: Lau Ga and Lau Hai San
In Hanoi (하노이 / 河内 / ハノイ) and the northern provinces, "lau ga" (chicken hotpot) is a cold-weather standard. The broth is made from a whole chicken simmered with ginger, rice wine, and sometimes shiitake mushrooms. It's mild and clean, closer to the Chinese influence that runs through northern Vietnamese cooking. "Lau hai san" (seafood hotpot) is popular year-round and allows the cook to showcase whatever is local and fresh that week.

How Seasons and Regions Shape the Pot
Vietnam's geography means lau is genuinely different by region. The South defaults to fermented and sour profiles — mam, tamarind, pineapple — reflecting the Mekong's produce. The North runs cleaner and brothier, often with more mushrooms and root vegetables. The Central region sits between the two: spicier than the North, less funky than the South.
Season matters in the North especially. Lau is a cold-weather preference in Hanoi — restaurants fill up from October through February. In Saigon, where temperatures barely shift, lau runs year-round without any seasonal logic.
How to Order Lau Without Getting Lost
Most lau restaurants in Vietnam work on a set format. You choose a broth (sometimes two — split-pot burners exist), then choose proteins from a printed menu or a displayed tray. Vegetables, noodles, and tofu usually come as a package. Dipping sauces arrive automatically: fish sauce with chilies, fermented shrimp paste, or a sesame-peanut mix depending on the regional style.
A few practical notes: the broth replenishment ("nuoc leo them") is usually free or very cheap — ask your server. Noodles go in last, not first, or they'll absorb all the liquid. If the pot is getting too salty, add the blander vegetables early and let them dilute it.

Where to Try the Canonical Versions
Lau Mam Ba Sau — Saigon (District 4): A no-frills Mekong-style lau mam spot that's been operating for decades. The fermented base is balanced and doesn't overwhelm. Around 180,000–220,000 VND per person.
De Nhat Viet Quan — Ninh Binh: Sits near the Trang An access road. Does lau de with fresh goat from local farms. The mam tom dipping sauce is made in-house. Lunch and dinner, 200,000–300,000 VND per person.
Lau Thai Co Lan — Da Nang: A busy, open-air spot near the Han River that runs a tight lau Thai menu focused on Central coast seafood. Loud, fast, and honest. Budget 200,000–250,000 VND per person for a full table spread.
Practical Notes
Lau is a long meal — budget at least 90 minutes. Most spots that specialize in it don't do quick turnover, so don't show up if you're on a schedule. If you're traveling solo or as a pair, some restaurants offer single-serve clay pot versions of lau ga or lau hai san, which is a reasonable workaround.
