Hi Qatari92, I know what you mean myself and my wife are British Expats living in Qatar and every so often we miss good homely traditional fish and chips like you would get from a chip shop in England, After searching around we found this small British Cafe slightly out of the center, it serves traditional style fish and chips pies etc, its pretty reasonable plus you get the ambiance. check it out on this link http://sandwichcellar.weebly.com/

Their are other places in Qatar for fish and chips we are still to try, if you Google fish and chips qatar you will find other comments and results.
