Challenge: Formatted Tavern Menu

Hello! I would to share the solution for the first challenge. Maybe someone wants to provide some sort of feedback:

const val LIST_WIDTH = 45

val menuList = File("data/tavern-menu-items.txt")
    .readText()
    .split("\n")

fun main() {
    val greeting = "Welcome to $TAVERN_NAME"
    val greetingLength = greeting.length
    val indent = constructString("*", (LIST_WIDTH - greetingLength - 2) / 2)
    print("\n$indent $greeting $indent\n\n")

menuList.forEach {
    var (_, item, price) = it.split(",")
    val itemWords: MutableList<String> = item.split(" ").toMutableList()

    itemWords.forEachIndexed { index, word ->
        when (word.toLowerCase()) {
            "of" -> {}
            else -> itemWords[index] = word.capitalize()
        }
    }
    item = itemWords.joinToString(" ")

    val space = constructString(".", LIST_WIDTH - item.length - price.length)

    print("${item.capitalize()}$space$price\n")
}
}

private fun constructString(symbol: String, rep: Int): String {
    val string = StringBuilder()
    repeat(rep) {
        string.append(symbol)
    }
    return string.toString()
}
