So far, the best place I've ever been to has to be Zeffirellis in Ambleside, UK.
I have been here three times now, and it is hands down my favorite place to eat.
The main dish I always order is The Zeffirellis Pecan and Cashew Nut Wellington, wrapped in puff pastry and served with mashed potatoes, roasted vegetables, and red wine.
It's absolutely delicious! Also, the dough balls dipped in garlic butter are amazing!
This place is my food heaven. If you ever visit Ambleside in the Lake District, you need to check this place out.
