A cafe cum bar beneath Tower Gateway railway bridge that cares just as much about its coffee as it does its craft beers. On tap and by the bottle they have Kernel Pale Ale, Camden Beer, a variety of Brewdogs and the gluten-free Mikkeller. To line stomachs Flock serve a variety of savoury dishes, including chunky burgers in brichoe buns with sweet potato fries on the side. They also have rich, sumptuous cakes for afters, or gelato if that's more your bag, and some other options to boot.
