The Britannia Inn is in a fabulous location. Elterwater is a really pretty little village a short drive from Ambleside. There are a few parking spaces on the lanes around the pub but we parked in the little car park just across the green, down the lane. I find it's usually best to book a table as it can get very busy. We ate in the restaurant (though on a previous occasion we ate in the bar opposite a beautiful roaring log fire so either is fine). It was fairly quiet in the restaurant as we dined early but there were reserved signs on all the tables, and there were plenty of people in the other areas of the pub ordering food. It is not a big place but the small size of the rooms makes it really cosy and gives you that sense of the fact you're in a building that is *well* over 200 years old.
The service was friendly and quick and there was plenty of choice on the menu, all of which is locally produced and/or homemade I believe. There was no real wait for food and it was all delicious when it arrived. We had soup and deep fried Brie in Thyme crumb for our starters and home-made shepherds pie and chicken and leek pie in a suet pastry for mains. We would have loved to have dessert as well but the pies were so huge we genuinely didn't have even the smallest amount of room to fit them in! The lad who took our order said afterwards that he did wonder when we ordered starters and then the pies!
Cost-wise, 2 pints of diet coke, 2 starters and 2 mains were a little under £48.
