Dim sum (點心) — the dishes — and yum cha (飲茶, "drink tea") — the practice — are the same thing described from different angles. Dim sum refers to the small plates; yum cha refers to the social meal of eating dim sum with tea. Both terms are used to describe going to a Cantonese restaurant on a Sunday morning, filling a table with bamboo steamers, and eating until you can't.
The tradition originated in teahouses along the Silk Road, where travelers would stop for tea and light snacks. It developed into a Cantonese culinary institution in Guangdong province, Hong Kong, and through the Cantonese diaspora into cities globally. Most dim sum restaurants globally are run by Cantonese families, and the menu is broadly standardized across Hong Kong, San Francisco, Vancouver, London, and Sydney.
How Yum Cha Works
Traditional cart service: At large traditional dim sum restaurants, carts are pushed through the dining room by servers. When a cart passes your table, you indicate what you want; the server marks your table's card and leaves the dish. This format is still used at many established Cantonese restaurants, particularly in Hong Kong and large diaspora communities. The excitement of carts is the randomness — you take what passes.
Menu/order sheet service: Many dim sum restaurants, particularly in cities outside established Cantonese communities, use paper order sheets or iPads. You check what you want; dishes arrive as prepared. Less theatrical but more reliable — you get exactly what you ordered.
Tea: Order tea first. Pu-erh tea (陳茶, aged fermented tea) is the traditional accompaniment — its robust, earthy character cuts through the fat and richness of the dishes. Chrysanthemum, jasmine, and oolong are also common. The waiter's first question will typically be what tea you want.
Timing: Dim sum service runs from roughly 8 AM to 2 or 3 PM at most restaurants. Peak time is 10 AM–12 PM on weekends — waits of 20–45 minutes are common at popular restaurants. Going at 8:30–9 AM avoids the wait and gets the freshest dishes.
The Essential Dim Sum Dishes
Steamed Dumplings
Har gow (蝦餃, xiā jiǎo, shrimp dumplings): The standard by which dim sum restaurants are judged. Whole shrimp in a translucent wheat starch and tapioca wrapper (not flour — wheat starch wrappers are nearly transparent when steamed). The wrapper should be thin and slightly glossy; the filling should have visible whole shrimp; the shape should have at least seven pleats on one side (a measure of the chef's skill).
Siu mai (燒賣, shāo mài): Open-topped cylinder dumplings — pork and shrimp filling in a thin yellow wonton wrapper, left open at the top, often garnished with a single roe or green pea. One of the most common dim sum dishes globally.
Xiaolongbao (小籠包, soup dumplings): Though specifically Shanghainese rather than Cantonese, now available at many dim sum restaurants globally. Pork filling with gelatinized pork broth in the filling — when steamed, the gelatin melts into soup. Eaten by carefully biting a small hole in the top, waiting for the soup to cool slightly, drinking the soup, then eating the dumpling. Do not bite in half first (the soup goes on your shirt or the table).
Cheung fun (腸粉, rice noodle rolls): Thin sheets of steamed rice noodle (bánh cuốn in Vietnamese) rolled around fillings — shrimp, beef, char siu pork, or vegetables. Served with sweet soy sauce and sometimes sesame sauce. The wrapper should be silky and delicate; the dish is simpler than dumplings but excellent when the rice noodle is fresh.
Steamed Buns
Char siu bao (叉燒包, BBQ pork buns): Exists in two forms:
- Steamed char siu bao: White, slightly fluffy steamed bun (the iconic round white bun with a slight split at the top) with sweet-savory BBQ pork filling inside. Soft all the way through.
- Baked char siu bao: Glazed with egg wash and baked golden brown; slightly firmer, shinier exterior. Often sweeter filling.
Both are standard; the steamed version is more common at traditional dim sum service.
Siu long bao (素包, vegetable bun): Vegetarian filling versions of steamed buns.
Lo bak go (蘿蔔糕, turnip/radish cake): Not a bun — a pan-fried cake made from shredded white radish and rice flour, pressed and cooked into a dense, slightly crispy exterior cake. Often seasoned with dried shrimp, sausage, or mushrooms. Served in slices; the exterior should be golden and crispy.
Fried Dim Sum
Wu gok (芋角, taro puffs): Deep-fried dumplings with a taro paste exterior (crispy, web-like exterior from the frying — the taro shell puffs into an open mesh structure) and a pork-mushroom filling inside. Very specific texture: the shell is almost crunchy-airy, then you hit the dense taro beneath, then the filling.
Ham sui gok (咸水角, fried glutinous rice dumplings): Half-moon shaped fried dumplings with a glutinous rice flour wrapper — slightly chewy, dense, with a pork-vegetable filling. Darker exterior from frying; slightly sweet from the rice flour.
Chun guen (春卷, spring rolls): Light, crispy fried wrappers filled with pork and vegetable mix. The universal appetizer across Chinese and Southeast Asian food, best when freshly fried.
Rice Dishes
Lo mai gai (糯米雞, sticky rice in lotus leaf): A golf-ball-to-fist-sized parcel of glutinous rice wrapped in lotus leaf and steamed. The lotus leaf imparts a subtle herbal fragrance to the rice. Inside the rice: pork, chicken, dried shrimp, Chinese sausage (lap cheong), mushrooms. One of the most substantial dim sum dishes; one per person is usually enough alongside other dishes.
Congee (粥, jook): Plain or topped rice porridge. At dim sum: served in individual bowls with toppings (preserved egg and pork, fish, pork and century egg). Lighter than dumplings; good for balancing heavier dishes.
Baked Pastries
Egg tarts (蛋撻, dan tat): A direct adaptation of Portuguese egg custard tarts from the Macau colonial connection — pastry shell (shortcrust or puff pastry) with silky, lightly sweet egg custard inside. The Cantonese version has a crispier shell and less caramelized top than the Portuguese original. One of the most universally loved dim sum items; usually sweet enough to function as dessert.
Pineapple bun with butter (bolo bao, 菠蘿包): Sweet bun with a crackle-topped exterior (the crackle resembles pineapple texture, though there's no pineapple in the bun) and a thick slab of cold butter inserted inside. Hong Kong bakery specific; appears at some dim sum service.
Dim Sum Etiquette
Pouring tea: Pour tea for others at the table before yourself. When someone pours tea for you, tap two fingers on the table (a gesture of thanks derived from a historical story about an emperor who disguised himself and couldn't bow in public).
The teapot lid: When you need hot water refilled, leave the teapot lid ajar or tilted. The server will refill it.
Marking the order card: At cart-service restaurants, your order card (which tracks what you've had) is collected at the end for the bill. Don't lose it and don't handle the cart servers' stamps.
Sharing: All dim sum dishes are shared at the table — placed in the center, served with chopsticks, eaten communally. There is no individual plate in traditional dim sum service.
Building a Balanced Dim Sum Order
A well-ordered dim sum table combines:
- 1–2 steamed dumpling dishes (har gow, siu mai)
- 1 bun (char siu bao, steamed or baked)
- 1 rice dish (lo mai gai or cheung fun)
- 1 fried dish (wu gok, spring rolls, or turnip cake)
- 1 vegetable dish (choi sum in oyster sauce, braised tofu)
- Egg tarts to finish
For 4 people, 8–10 dishes total is a generous meal; 5–6 dishes is adequate.
