Artoplasia Greek Bakery

You walk past the Abbey station end of London Road and suddenly there's the smell of butter and phyllo hitting you—that's your cue to stop. Artoplasia does what British bakeries mostly ignore: they make spanakopita that doesn't taste like it's been sitting under a heat lamp, koulouria with proper sesame, and baklava that's actually crisp. The counter's small, the queue moves fast, and locals have already figured this out (4.8 stars doesn't happen by accident). Grab whatever's still warm, sit on the bench outside or take it home—either way, you're eating something genuinely good.
