Sainsbury's

You wouldn't expect to find yourself genuinely excited about a supermarket bakery, but this Wilton Road branch has somehow cracked the code. Walk past the usual grocery aisles and you'll discover their in-store bakery turning out proper croissants, decent sourdough, and surprisingly good pastries that put many standalone bakeries to shame. The location helps – tucked between Victoria Station and the Thames, it serves everyone from commuters grabbing breakfast to Pimlico residents doing their weekly shop. What sets it apart is the sheer consistency and the fact that they're baking throughout the day, so you're likely to catch something warm coming out of the ovens. The coffee's perfectly serviceable too, making it a genuinely viable pitstop whether you're rushing for a train or just need somewhere reliable that's open late.
