Lumpy Hill Adventure Playground is normally reserved for kids - but adults get a day to check it out at this ice cream festival where Thai ice cream rolls, boozy lollies, liquid nitrogen and wacky avocado, burnt toast, bacon and lemon meringue all appear on the menu.
Entrance is free when you check in on the Yelp app (and if you want to support Islington Play, you can make donations on the day).
