McDonald's

If you're heading through the A20 corridor and need a quick pit stop, this McDonald's at the service area is genuinely handy – it's got everything you'd expect done reliably, and locals swear by it for a fast refuel between journeys. The location makes it perfect if you're traveling through Orpington or Swanley and don't want to venture off the main road, though fair warning: service area prices come with the territory.
