When staying in Coverack, The Lizard we always try to make time to pop into Archies Loft. It is owned by Roskillys the local ice cream family, and they basically sell freshly made cookies, pizzas when they are ready and ice cream. There is no indoor seating, but a couple of tables and chairs outside to sit and munch on your homemade goodies.
The seagulls look well fed (and unusually quiet!)
I love it there.
