Yeah, there's quite a few, but it doesn't always mean they are better run than Vietnamese places, although getting your point or view across to them is easier i guess.
Off top of my head, all Indian restaurants(Indian Chef) except Food Shop 45, but that does a damm good curry.
Finnegans, owner is Moonie but has expat bar staff. Daluva run by expats, same with Jafa at Ciputra.
Half the Italian joints in town, alfresco's chain/group run by Aussies.
I could go on, but if you, like Alpha says, give us your insight to why you'd like to know, i could be more specific.
