Walk into any pho restaurant and the menu will have a list of numbers or combinations -- Pho 1, Pho Dac Biet, Pho Tai Chin, Pho Tai Nam Gau. If you do not know what those words mean, you are guessing. This page fixes that. Every cut explained, what it tastes like, who it is for, and how to order it with confidence.
A note before we start: not every restaurant carries every cut. Smaller or busier kitchens often simplify. But knowing the full vocabulary means you can always ask, and always understand what arrives in your bowl.
Rare beef
Tai is thinly sliced raw beef -- usually eye of round or sirloin -- that arrives in your bowl pink and almost translucent, draped over the noodles. The moment the hot broth hits it, it begins to cook. Within thirty seconds, it turns from pink to pale. Within a minute, it is cooked through.
This is intentional. The correct approach is to eat it quickly, before it overcooks in the residual heat. Tai at its best is tender and silky with a clean, delicate beef flavour -- not chewy, not gamey, not strong. It is the most approachable cut in the bowl and the one most Westerners default to, for good reason.
Eat the tai first, before anything else. It is time-sensitive. Once it overcooks it turns grey and tough and you have lost the point of it. Stir it gently into the broth once, then start eating.
Some menus list tai nam -- rare beef plus a softer, flank-style cut that is more cooked. Or tai sach -- rare beef plus tripe. These combinations are common and worth exploring once you are comfortable with tai on its own.
Well-done brisket
Chin is brisket that has been simmered for hours until it is completely tender and falling apart. It is lean, clean, and deeply familiar -- if you have ever had a good beef stew, you know roughly what chin tastes like. No surprises here.
The texture is soft but not mushy -- it holds together when you pick it up with chopsticks but gives immediately when you bite into it. The flavour is mild and savoury, absorbing the broth it has been sitting in. Chin is the safest order on the menu and an excellent default for anyone trying pho for the first time.
Ordering tai chin -- rare beef plus well-done brisket -- is one of the most popular combinations on any menu and a great way to experience the contrast between the two in a single bowl.
Fatty brisket
Gau is the same brisket as chin but from a fattier section -- heavily marbled with fat and connective tissue that has dissolved into something almost gelatinous after hours of simmering. Where chin is lean and clean, gau is rich and unctuous. A piece of gau almost melts on the tongue.
The fat in gau also enriches the surrounding broth as you eat. By the time you are halfway through a bowl with gau in it, the broth around it has taken on an extra silkiness. This is not a drawback -- it is the point. Gau is for people who understand that fat is flavour.
If you are used to avoiding fatty meat, try gau once before deciding. The fat here is slow-cooked collagen, not raw grease -- it behaves completely differently and converts most sceptics on first encounter.
Tripe
Sach is honeycomb tripe -- the stomach lining of the cow, recognisable by its distinctive ridged, grid-like surface. In a good pho kitchen it has been thoroughly cleaned, blanched, and simmered until tender. What you get in the bowl is pale, mildly flavoured, with a satisfying chew that is somewhere between firm tofu and calamari.
The flavour of sach itself is subtle -- almost neutral. What makes it interesting is texture and its ability to carry the broth. Each honeycomb cell traps a small pool of soup. When you bite through it, you get a little burst of broth along with the chew. It is a textural experience as much as a flavour one.
Sach is the cut that divides people most sharply. Those who love it really love it. Those who do not usually object to the texture rather than the taste. If you are curious, ask for a small amount on the side before committing to a full portion in your bowl.
Quality matters enormously with tripe. Well-prepared sach in a good kitchen is a revelation. Poorly cleaned or overcooked tripe is not. If a restaurant is busy and the broth is clearly made in-house, the tripe is almost certainly going to be good.
Tendon
Gan is beef tendon -- the connective tissue that holds muscle to bone. After many hours of simmering, it transforms from something tough and fibrous into something almost impossibly soft. Properly cooked gan has a deep, wobbly, gelatinous quality. It barely requires chewing. It dissolves.
The flavour is concentrated and beefy in a way that muscle meat rarely achieves -- all that collagen breaking down into gelatin produces a richness that coats your mouth. If gau is the richest conventional cut, gan is richer still, and more unusual.
Tendon is not for everyone. The texture is unlike anything in Western food traditions, and that unfamiliarity is genuinely offputting for some people. But for those who come around to it, gan is often the cut they look forward to most.
Gan is a good indicator of how long a kitchen simmers its broth. Tendon that is still tough or rubbery has not had enough time. Tendon that dissolves almost without chewing means this kitchen put in the hours. Use it as a quality signal.
Beef balls
Bo vien are Vietnamese beef meatballs -- but nothing like the soft Italian-American meatball. They are made from beef that has been pounded or processed until the proteins tighten, producing a dense, springy ball with a satisfying snap when you bite into it. The texture is closer to a good fish ball or a Chinese beef ball than anything Western.
The flavour is intensely beefy and well-seasoned -- savoury, a little peppery, with none of the subtlety of the other cuts. Bo vien hold their shape and their heat well, making them a reliable constant in the bowl as everything else evolves around them.
Bo vien are excellent dipped in hoisin sauce or sriracha on their own before they go into the broth. Many regulars eat them separately from the rest of the bowl precisely because the bold seasoning can overpower a delicate broth if left to soak too long.
The house special combination
Dac biet means "special" in Vietnamese, and on a pho menu it almost always means the same thing: everything. All the cuts in one bowl -- tai, chin, gau, sach, gan, bo vien -- in whatever combination that particular kitchen considers its signature offering.
Ordering dac biet is the right move when you want to understand a restaurant properly. You see every cut side by side in the same broth. You can taste the differences directly. You learn which cuts you prefer without having to come back six times. It is also usually the best value on the menu.
The bowl will be large. Come hungry.
On your first visit to any new pho restaurant, order dac biet. You will learn more about that kitchen in one bowl than you would from three separate visits ordering single cuts.
How to order with confidence
Most pho menus in North America and Australia use either English descriptions, number codes, or the Vietnamese names above. The numbers vary by restaurant and mean nothing across different places -- Pho 1 at one restaurant is completely different from Pho 1 at another. Ignore the numbers, use the names.

When in doubt: dac biet. You will figure out your preferences from there.
