You're spoilt for choice! The Mortal Man at Troutbeck - terrific beer garden if the weather's right. Old Dungeon Ghyll or Stickle Barn in Great Langdale. Wainwright's at Chapel Stile. The Watermill at Ings, just east of Windermere - it even has its own brewery. People rave about the Drunken Duck near Hawkshead, though I'm afraid I've never been.
