The dish consists of an omelette with a filling primarily composed of small Pacific oysters.

Depending on regional variations, a savory sauce may then be poured on top of the omelette for added taste.

[citation needed] Spicy or chili sauce mixed with lime juice is often added to provide an intense kick.

The former is popular in Fujian and Taiwan, while latter is the usual style seen in Hong Kong and Chaoshan areas.

In Bangkok, notable areas for oyster omelettes include Talat Wang Lang near Siriraj Hospital and Wang Lang (Siriraj) Pier in Bangkok Noi where there are two restaurants,[8][9] Yaowarat neighborhood, where there is one Michelin-Bib Gourmand restaurant[10][11] with Charoen Krung neighborhood in Bang Rak, among others.
