Regional Cambodian cuisines in the LA diaspora

No LA Cambodian restaurant explicitly identifies its dishes or concept with specific Cambodian provinces. The closest is Gamboge in Lincoln Heights, which highlights its num pang sandwich as a Cambodian staple but does not link it to any particular province ^[1]. Gamboge’s food draws on general Cambodian flavors (kroeung paste, Mekong River ingredients) and the chef’s family memories, not a provincial origin ^[1]. Hak Heang Restaurant in Long Beach serves authentic Cambodian cuisine but does not mention provincial ties ^[2]. The other sources are a Wikipedia article on num banhchok (a noodle dish) ^[3] and a recipe for samlor korko (a mixing soup) ^[4]; neither discusses LA restaurants or provincial origins. To identify provincial affiliations, one would need restaurant menus, chef interviews, or reviews that explicitly state provincial affiliations (e.g., ‘Battambang-style samlor kako’ or ‘Kampong Cham river fish dish’).
