All Bar One Portsmouth

There aren’t many bars that can say they overlook the deserves-a-spot-on-your-Feed waters of Gunwharf Quays Marina, but here at All Bar One Portsmouth, it’s our claim to fame – alongside our delicious dishes & drinks, of course.

While you’re sipping on your morning coffee, grazing on our tapas menu, or soaking up the sun on our terrace with a cocktail in hand, enjoy the views of Portsmouth Harbour, the ever-so-eye-catching Spinnaker Tower, and watch the locals simply loving life on the water.

If you need a little longer to bask in this fabulous atmosphere, settle in with a few friends for a delicious lunch or Bottomless Brunch, tempting you to spend many afternoons by the ocean.
