I believe they were asking whether or not "ethnic" is the correct term.

"Foreign food" or "foreign restaurant" seems to be the norm where I live, but maybe I'm uncultured. "Ethnic" wouldn't offend anyone I don't think.

Could be. "Ethnic" sounds to my ear a lot less possibly offensive than "migrant" given the current climate.
