[1][2] In addition to the original restaurant in Southeast Portland, the business operated in Beaverton, Estacada, and Sandy, and specialized in dim sum.

The original restaurant was located in the strip mall King Plaza on Division Street in the southeast Portland section of the Montavilla neighborhood,[3] and had a large dining room.

[5] The menu featured dim sum and included chicken feet, congee, crab,[6] dumplings, har gow, noodles, Peking duck, pork barbecued ribs, pork buns, pot stickers, rice cakes, beef rice-noodle rolls[7] and spring rolls,[8] tofu,[9] turnip cakes,[10][11] and wontons.

[28] Jamie Goldberg of The Oregonian noted some of the restaurant's employees "struggled to overcome language barriers when navigating Oregon's dysfunctional unemployment benefits system".

In 2005, Grant Butler of The Oregonian wrote:At last, Portland gets a temple to Cantonese cuisine with the arrival of this large Chinese restaurant.

[36] Kathy Baruffi included Wong's King in USA Today's 2009 list of 10 "great places to welcome prosperity", as recommended by Martin Yan.

Despite the long lines, servers are friendly, the food emotes pure Hong Kong goodness and there's no rushing you out the door, an unfortunate practice in too many popular dim sum places.

"[40]Wong's King was named runner-up in the Best Chinese Restaurant category in Willamette Week's annual readers poll in 2007.

[44] Eater Portland included Wong King's spicy crab in a 2013 list of "the nine must-try Asian dishes on SE 82nd Avenue".

[45] In 2022, the same website's Seiji Nanbu and Brooke Jackson-Glidden called Wong's King a "Portland dim sum legend".
