whats wrong?

Question

why is this 2d ArrayList is putting all the smaller normal arrayLists in one bracket ("[ ]")?

code:

import java.util.*;
public class Main
{

public static void main(String[] args){

ArrayList <String> drinks = new ArrayList<String>();
drinks.add ("fanta");
drinks.add ("sprite");
drinks.add ("coca cola");

ArrayList <String> burgers = new ArrayList<String>();
drinks.add ("burger");
drinks.add ("cheeseBurger");
drinks.add ("hamBurger");

ArrayList <String> markets = new ArrayList<String>();
drinks.add ("kopshop");
drinks.add ("ramiLevi");
drinks.add ("yeshHessed");

ArrayList <ArrayList<String>> food = new ArrayList();
food.add (drinks);
food.add (burgers);
food.add (markets);

System.out.println(food);

}

}
