Ole & Steen

You're wandering through Crossrail Place — that glassy corporate thoroughfare in Canary Wharf — when the smell of butter and fermentation stops you dead. This is Ole & Steen, a Danish outfit that takes their baking seriously enough to make you forget you're surrounded by investment banks. The sourdough has real tang, the croissants shatter properly, and their cinnamon swirls are the kind of thing you'd queue for in Copenhagen. It's not trying to be cool; it just happens to be doing bread better than most places charging twice the price in trendier postcodes.
