Enh, maybe.
But a few counterpoints:
1. We can assume C.S. Lewis intended a lot. Don't confuse the ease of his style with careless choices.
2. Have you read The Horse and his Boy? C.S. Lewis specifically talks crap about food that sounds Arab. Like almond chicken.
3. Come on, "Turkish Delight"? It sounds like a kinky sexual position. "Turkish" has a strong association with fascism and brutality in--specifically upper-class--Western culture, (cf., Igby Goes Down, New York City Cops, Lawrence of Arabia).
