We found the Mackerel Sky by accident when looking for somewhere to eat in Penzance. What a lucky find - the upstairs restaurant is atmospheric and warm, and the food we had was delicious. We both tried the chargrilled halloumi cheese salad with raspberries and grapefruit. It sounded a bit strange but it was amazing - I will be trying to recreate this myself in the near future! Thanks for a lovely evening - you deserve to be number one on this list in our opinion.
