Pub · Chelsea
The Builders Arms is a relaxed pub restaurant tucked away on a quiet Chelsea street, the sort of place that feels genuinely local rather than trying too hard. There's outdoor seating if the weather plays along, and getting in with a buggy is straightforward enough. It's worth noting there's no dedicated children's menu or highchairs, so it's probably best suited to families with older kids who are happy eating from the main menu.

The secret to a calmer meal out? Something to do that isn't a phone. Each pack is full of screen-free bits and bobs to keep little hands busy at the table and buy you a proper sit-down. Three printable packs, one for each age (toddler, preschool, primary) — free, straight to your inbox.
