My boyfriend and I have been on a mission for about two years now to find the best burger in London... We have visited some brilliant places but Patty and Bun is right up there for us for being one of the Best. Fairly priced for a fairly good portioned burger which is mouth watering and sheer awesome! Their fries are also really nice which just completes the package. Service is normally excellent. We've never waited more than 15 minutes for our food, even on a busy evening (and they are always busy) and staff are always friendly and smiley. Can't recommend the place highly enough! Big fan!
