Charters Bar in Peterborough. It's a floating barge just opposite Peterborough United ground as you come over the bridge.
They have a beer garden outside the barge based on a Munich beer garden with loads of tables in a field and an under cover band stand that gets packed on nice days in summer.
I'm like a kid in a sweet shop with the amount of real ales and bottled trappist ales etc on offer at the bar inside the barge.
I go up to peterborough every year for the biggest beer festival in the UK every August bank holiday weekend. They have a massive beer festival on what is the equivalent of Coopers field in Cardiff and its under 6 massive circus tents. It's a gin tent, wine tent, and cider and Perry tent along with the biggest selection of bottled beers and ales from all over the world.
Live music every day and night in the music tent.
