Restaurant Overcharging and Menu Tricks

Eating out in Vietnam is one of the cheapest reliable pleasures in the world. The vast majority of restaurants, including the ones in tourist areas, charge what the menu says and total the bill correctly. The exceptions cluster in a few predictable places and use a small repertoire of tricks. Knowing them is mostly about saving yourself a mild irritation, not protecting yourself from anything serious.

Where it tends to happen

Three zones produce the bulk of complaints:

• Bùi Viện walking street in HCMC, especially the seafood and "tourist Vietnamese" places facing the strip.
• Old Quarter fringes in Hanoi — particularly the streets immediately around St Joseph's Cathedral, parts of Tạ Hiện, and the late-night spots catering to bar crowds.
• Hoi An old town fringes — the streets just outside the lantern core, and a handful of riverside seafood places.

Local-facing eateries, even in the same cities, rarely do this. The pattern is restaurants that depend on one-time tourist customers rather than repeat business.

The common tricks

A short field guide to what shows up on suspect bills:

• Menus without prices. Often handed over with a smile and a "we have specials". The specials are priced after you've eaten.
• "Market price" seafood (giá theo thị trường). Legitimate at high-end restaurants where it's noted clearly. In tourist zones, it can mean five to ten times the going rate. If you want the lobster, ask for a written price per kilogram and confirm the weight before it's cooked.
• Stealth additions. Wet towels, peanuts, a plate of pickles, a fruit platter "compliments of the chef". Some are genuinely free, some are billed at 50,000–100,000 đồng each. If you didn't ask, push the plate back gently before you touch it.
• Drink swaps. You order the small beer, the large arrives. You order the local rice wine, an imported spirit arrives. The bill reflects what came, not what you asked for.
• Service-charge stacking. A 5% or 10% service charge, plus 8% VAT, plus an expected tip. Each is sometimes legitimate on its own; the stacking is the issue when none of it was mentioned.
• Phantom items. Three beers on a bill where you had two. Easy to miss if the bill is handwritten in Vietnamese.

How to keep the bill honest

A few habits make almost all of this disappear:

• Ask for the menu with prices. "Menu có giá, làm ơn." If they don't have one, eat somewhere else. It takes thirty seconds to find another option.
• Photograph the menu before you order. This stops the most common dispute — "that's not what was listed" — before it starts.
• Confirm the seafood price by weight, in writing if possible. Ask to see the fish or shellfish before it goes to the kitchen and have the weight written down.
• Refuse anything you didn't order. Politely, but immediately. Once it's on the table for a few minutes, the argument gets harder.
• Ask for an itemised bill ("hóa đơn chi tiết"). Read it before paying. Drinks, food, service charge, tax, and the total should all be on separate lines.
• Pay what you owe, not what you don't. If a line is wrong, point at it calmly. Most disputes resolve quickly when you stay polite and specific.

What to do if it happens

If the bill is clearly padded and the staff won't adjust it, your leverage is reputational. Pay what is fair — what the menu (or your photo of it) shows — leave the disputed amount as a written note, and walk out. Confrontation almost never improves the outcome. Once you're outside, a Google Maps review with a photo of the bill and the menu is the single most effective response: it is read by the next thousand visitors and it directly affects the restaurant's ranking. Vietnamese restaurant owners take Google reviews seriously, partly because the platform is now the de facto guidebook for most foreign visitors.

For card payments, you can sometimes dispute charges through your bank if the venue is clearly billing fraudulently — keep the photos.

For context: most meals in Vietnam, even tourist ones, will be honestly priced and excellent value. The places that do this stand out partly because the surrounding norm is so straightforward. If you find yourself getting overcharged twice in a row, the issue is probably the street you're eating on rather than the country. Step a block or two away from the strip and the problem usually evaporates. If you're paying cash, see money exchange scams for a related set of tricks at the other end of the transaction.
