Dialogue Cafe @ RDCS, UEL

Part community centre, part art gallery and part event space, this Canning Town café is as much a neighbourhood gathering place as a coffee stop — and it's clearly doing something right, holding a 4.8 rating from 52 reviews. Dogs are welcome and both dine-in and takeaway are on offer, though you'll need sharp timing to visit: doors open only on Monday mornings, from 9 to 11.
