Laravel - Checking whether a models child has a specific id - php

Question

I am trying to create a 'favouriting' system where i need to check if the 'dish' is already favourited or not. I am having some troubles figuring out how to do so.
I am on my 'Resturant' show page, which contains the following:
Resturant Controller:
public function show($id)
{
$resturant = Resturant::find($id);
$favourites = Favourite::all();
return view('resturants.resturant_show')->with('resturant', $resturant)->with('dishes', Dish::all())
->with('favourites', Favourite::all());
}
Resturant_show:
<div class="row row-cols-1 row-cols-md-3 g-4 m-3">
#foreach ($dishes as $dish)
#if ($resturant->id == $dish->resturant_id)
<div class="col">
<div class="card h-100">
//accessing $dish->id etc here, taken out to reduce snippet size
#foreach ($favourites as $favourite)
#if ($dish->id == $favourite->user_id)
<form method="POST" action='{{ url("favourite/$favourite->id") }}'>
{{ csrf_field() }}
{{ method_field('DELETE') }}
<button
class="btn btn-outline-danger
type="submit" value="Delete"></3</button>
</form>
#else
<form method="POST" action='{{ url("favourite/$favourite->id") }}'>
{{ csrf_field() }}
{{ method_field('DELETE') }}
<button
class="btn btn-outline-danger"
type="submit" value="Delete"><3</button>
</form>
#endif
#endforeach
<button type="button"
class="btn btn-outline-primary">
${{ $dish->price }} <span
class="rounded-pill bg-danger">Discount
#%</span>
</button>
</div>
</div>
</div>
#endif
#endforeach
</div>
#foreach ($favourites as $favourite)
#if ($dish->id == $favourite->user_id)
This is where I am looking to only display a single button (currently one foreach as I don't know how to find the right favourite data).
My relationships look like such:
Favourite
//Relationship with user
function user() {
return $this->belongsTo('App\Models\User', 'user_id');
}
//Relationship with dish
function dish() {
return $this->belongsTo('App\Models\Dish', 'dish_id');
}
Dish
//Relationship with resturant
function resturant() {
return $this->belongsTo('App\Models\Resturant', 'resturant_id');
}
//Relationship with favourite
function favourite() {
return $this->hasMany('App\Models\Favourite', 'favourite_id');
}
Resturant
//Relationship with user
function user() {
return $this->belongsTo('App\Models\User', 'user_id');
}
//Relationship with dish
function dish() {
return $this->hasMany('App\Models\Dish', 'dish_id');
}
