Import Market for foods... where are they? (Cairo)

Ok so I am looking for a few more supermarkets that deal mostly with imported goods and foods (mostly food). I am familiar with Royal House, Spinneys as well as Metro.. Is there anything in the Giza area? We left Cairo and Royal House is just tooo far now for us. Spinneys and Metro just really don't have the kind of stuff or quantity of American imports.. anyone have more suggestions?
