I'm trying to compile a list of good or even (dare I hope?) excellent "ethnic" restaurants in Plymouth and immediate environs (no more than a 10 or at the very most 15 mile radius). I'm putting "ethnic" in scare quotes because although obviously Italian, French, Irish, English are ethnicities, I'm interested in Portuguese, Mexican (as opposed to Tex-Mex), Vietnamese, Thai, Korean, and whatever else might be good out there. Hole in the wall is totally fine. I know the pickings are slim but is this a completely lost cause?
