Sainsbury's

You might not expect much from a supermarket bakery, but the one tucked inside this Cable Street Sainsbury's consistently turns out decent bread that actually tastes like it was made today. The croissants arrive warm in the morning, and their sourdough has proper tang and crust – none of that spongy nonsense you get elsewhere. The selection changes throughout the day, so timing matters if you're after specific items. Their doughnuts disappear fast on weekends, and the focaccia is genuinely good enough to serve at dinner parties without shame. Yes, it's still a supermarket counter, but when you're doing the weekly shop anyway and fancy something fresh for breakfast, it beats trudging into town for overpriced pastries.
