Duck and Waffle, Heron Tower

To escape the humdrum and heat of the city, why not head to the restaurant atop the Heron Tower and give yourself a true sense of perspective.
With views to The Shard, this panoramic restaurant is the highest in the city and worth a visit for the views alone. But it's not just wide vistas that attract Londoners to Duck and Waffle. Their brunch menu features a huge range of Belgian Waffles with all the trimmings, and of course their iconic duck/waffle combination, made with crispy leg confit and served with mustard maple syrup. There's also the scrumptious sounding wild cornish pollock meatballs, or, for a sweet round-off to a hearty breakfast there are maple caramel apples topped with cinnamon ice cream. 
Best of all, for those allergic to early mornings or prone to midnight munchies, Duck and Waffle serves up its brunches 24 hour a day.
