Hilarious pub chalk boards have been around almost as long as pubs. But the art form, if such it can be called* seems to have accelerated in recent years, spilling over into coffee shops and restaurants. We now defy you to walk along any London high street without smirking or scoffing at some barista’s witticism. We’ve rounded up some recent discoveries in the gallery above. We’ll add to the gallery over time, with reader favourites to be sent to email@example.com, or uploaded to the Londonist Flickr pool. Although we’ve stuck to pubs above, we also welcome signs from other gag-happy venues.
