Its awkward seating arrangements may not be London's most accommodating, but bum deals are rare when it comes to head honcho Richard Woods’ singularly experimental creations at Duck & Waffle. Obscure ingredients boldly go where no mixologist has gone before: charred dandelion-root 'expresso', burnt toast, 'damp gin,' asparagus ends and cut grass are not for the timid. But if you duck the venue’s over-zealous waffle ('urban foraging vs urban decay'), you'll be amply rewarded. The likes of Pine Needle Lemonade, Avocado Aperitivo (Patrón Reposado, chocolate, toasted walnut, avocado skin infusion) and Hay! (Jack Daniel's, maple, salted caramel and hay infusion) just about justify their vertiginous cost at this hotspot’s perch atop Heron Tower. To eat, nibble on BBQ spiced pig’s ears, bacon-wrapped dates or crispy polenta with Parmesan and truffle. Just add some truly astounding City views and you’ll gather this is no lame duck.
