Harrisburg - Ethnic Food
Passage to India and Rose's (both from above) are both pretty good. Do note that Rose's closes pretty early; I think 8:30 p.m.
I would say that Aangan (www.aanganindiancuisine.net) is slightly better Indian than Passage.
La Kasbah on second is pretty good. The guy is Moroccan. It is primarily kabobs and tangines. I beleive that the the ownership has switched from one brother to another. I have not been there since but I doubt it is a huge change. http://www.kasbahdeli.com
Still the best restaurant overall, in my opinon, would be Suba. It is a tapas restaurant (so Spanish influenced but probably not ethnic in the manner you mean). http://www.mangiaqui.com that is actually for a sister restaurant but Suba's menu can be accessed from there as well.
