Stef's point is a good one, as are all the others made in this fascinating thread. But 'immigrant' still leaves us with the conundrum of English, Irish, Australian and other immigrant-but-English-speaking populations, as Pan points out. How much of 'ethnic' has to do with perceived 'exoticism,' in either ingredients or technique? To me, the reason Tabla is not 'ethnic' isn't price point. It's auteurism (is that a word?). Floyd's food reflects his own sensibilities more than it does the food of India, although that influence is certainly apparent as well. I don't think any of us would call El Bulli 'ethnic' either. I'm tempted to say that cuisines typically considered ethnic are more rooted in home cooking - or attempts to replicate a feeling of home - than in restaurant cooking. That's imperfect too, I know.
