I just spent 10 minutes zooming into every dish and menu item from a Cambodian restaurant in Seattle to check if it was truly serving the Cambodian Teochew food that I was wanting (very similar to the Vietnamese Teochew and Singapore Teochew food I like). I think it is, but the best way to confirm is to check by eating there (tomorrow).
One of the challenges of looking for familiar foods is I can find it across many 'countries' but it's the same dish but with a different name in another language. There are some hints, though.
Kuay teow in Thai, Kuy teav in Khmer, kway teow in Malay, all from the same root words in Teochew
