Laravel Cart not picking up food price - laravel

Question

Am building an ordering system for restaurants
When one clicks order here it takes the user to the cart page>this is the link that takes the user to the cart page
<p class="btn-holder"><a href="{{ route('restaurants.cart',$restaurant->id)}}" class="btn btn-primary btn-block text-center" role="button" > Order this</a> </p>
but my cart page isn't displaying the food price.It displays it as 0 yet the price exists.
<table id="cart" class="table table-hover table-condensed">
<thead>
<tr>
<th style="width:50%">Product</th>
<th style="width:10%">Price</th>
<th style="width:8%">Quantity</th>
<th style="width:22%" class="text-center">Subtotal</th>
<th style="width:10%"></th>
</tr>
</thead>
<tbody>
<?php $total = 0 ?>
#if(session('cart'))
#foreach(session('cart') as $id => $details)
<?php $total += (int)$details['price'] *(int)$details['quantity'] ?>
<tr>
<td data-th="Product">
<div class="row">
{{-- <div class="col-sm-3 hidden-xs"><img src="{{ $details['photo'] }}" width="100" height="100" class="img-responsive"/></div> --}}
<div class="col-sm-9">
<h4 class="nomargin">{{ $details['name'] }}</h4>
</div>
</div>
</td>
<td data-th="Price">{{(int) $details['price'] }}</td>
<td data-th="Quantity">
<input type="number" value="{{ $details['quantity'] }}" class="form-control quantity" />
</td>
<td data-th="Subtotal" class="text-center">{{(int) $details['price'] *(int) $details['quantity'] }}</td>
<td class="actions" data-th="">
<button class="btn btn-info btn-sm update-cart" data-id="{{ $id }}"><i class="fa fa-refresh"></i></button>
<button class="btn btn-danger btn-sm remove-from-cart" data-id="{{ $id }}"><i class="fa fa-trash-o"></i></button>
</td>
</tr>
#endforeach
#endif

<tfoot>
<tr class="visible-xs">
<td class="text-center"><strong>Total {{ $total }}</strong></td>

This is the Foods controller and function addToCart which adds items to cart
public function addToCart($id){
$food = Food::find($id);
if(!$food) {
abort(404);
}
$cart = session()->get('cart');
// if cart is empty then this the first product
if(!$cart) {
$cart = [
$id => [
"name" => $food->food_item,
"quantity" => 1,
"price" => $food->price,
]
];
session()->put('cart', $cart);
return redirect()->back()->with('success', 'Product added to cart successfully!');
}
// if cart not empty then check if this product exist then increment quantity
if(isset($cart[$id])) {
$cart[$id]['quantity']++;
session()->put('cart', $cart);
return redirect()->back()->with('success', 'Product added to cart successfully!');
}
// if item not exist in cart then add to cart with quantity = 1
$cart[$id] = [
"name" => $food->food_item,
"quantity" => 1,
"price" => $food->price,
];
session()->put('cart', $cart);
return redirect()->back()->with('success', 'Product added to cart successfully!');
