Scala - Getting the error scala.xml.NodeSeq

I am trying to write code to import XML file. I am missing some basic things -- Here is the code.

import xml._

case class Menu(name: List[String])
case class BreakFastMenu(food: List[Menu], price: List[Menu], des: List[Menu], cal: List[Menu])

def toMenu(node : Node): Menu = {
    val menuChart = (node \ "food")
    Menu(menuChart)
}

def toBreakFastMenu(node: Node): BreakFastMenu = {
    val name = (node \ "name").map(toMenu).toList
    val price = (node \ "price").map(toMenu).toList
    val des = (node \ "description").map(toMenu).toList
    val cal = (node \ "calories").map(toMenu).toList
    BreakFastMenu(name, price, des, cal)
}

val menuXML = XML.loadFile("simple.xml")
val food = (menuXML \ "food").map(toBreakFastMenu).toArray
food.foreach(println)

And the XML file is here - simple.xml Getting the error as

MenuXML.scala:9: error: type mismatch;
 found   : scala.xml.NodeSeq
 required: List[String]
        Menu(menuChart)
             ^
one error found

Can anyone sort me out what the basics I am missing .
