Megan's at the Sorting Office (Islington Square)

You're walking into Islington Square and suddenly you're in this massive, light-filled space that used to sort the Royal Mail. It's the kind of restaurant that doesn't need to try too hard because the bones of the building do half the work for it. Floor-to-ceiling windows, exposed brick, that brilliant post-industrial vibe—but it never feels cold or try-hard. The Mediterranean menu spans from proper wood-fired pizzas to seafood that's handled with real care, and they've clearly got their sourcing sorted. It's the sort of place locals genuinely book weeks ahead for, not because it's fashionable, but because the food and the room just work together.
