Quick dim sum 101

Dim sum or yum cha (Cantonese for "drink tea") consists of an assortment of shared, small steamers and plates full of buns, dumplings, rice and fried bites which travel on pushcarts table-to-table as you sit happily sipping on bottomless pots of tea. In other words, it's an all-you-can-eat, rolling Chinese buffet best shared with a large group.

Beating the crowds

Like many Atlanta restaurants on Sunday morning, dim sum joints around the metro tend to have lines out the door, especially those along Buford Highway. Brunchers in the know arrive between 10:30 a.m. and 11:30 a.m. Dim sum is traditionally served from 10 a.m. to 3 p.m. Very few restaurants offer reservations.

No menu, and that white ticket

Unless you ask for one, there is usually no menu for dim sum. Once seated, a white ticket will be placed on your table. This ticket is used by the cart servers to check off the items you choose. Be sure to order a pot of tea for the table. When you run out, simply ask for more.

Ready, set, dim sum

As soon as your hind end hits the chair, the pushcarts start rolling. Don't be afraid to ask questions if you're unsure of an item. The servers will give (very) brief descriptions of their carts when they arrive to deliver the goods. Each steamer or plate contains between three and four bites.
