Around about the Christmas / New Year period, Mr B returned from a walk around the block bouncing with excitement because a new coffee window had opened up just around the corner from our house. It is by these small milestones that we measure out life’s joys.

We love a good coffee window around these parts. When you push a double pram weighed down by more than 20 kilograms of children (and probably an afternoon’s worth of grocery shopping) around town and you’re desperate for a coffee, not having to navigate doors and steps and tables and chairs and other diners to purchase said coffee is pretty appealing.

Cafe Bü is narrow and tiny and utterly charming. The owners have made clever use of every inch of space. The coffee window is a place for my friends on the pram-brigade get their caffeine fix, along with a host of cyclists and joggers and other coffee-loving passers by. For those who want to stop, a handful of converted crates offer limited seating outside the window and, inside, stools line a second window where punters can sip their 5 Senses coffee from the warmth of the tiny cafe.

But the best part of this cafe is its little rooftop courtyard. Stairs through the back of the shop lead up to a narrow rooftop with a bar that looks out over the street, and cleverly-designed tables set against the rear-facing wall, that can fold up and down to suit groups of different sizes.

Yesterday while the children were in care, I took my computer and notes up to the sunny Cafe Bü rooftop for a working lunch, with a side of bird’s-eye view of Carlton North. After a bitterly-cold morning, the day had turned mild, windless and sunny. Perfect rooftop dining weather. A black and white stretched awning kept the worst of the glare out of my eyes, and heaters lined the back wall, although we didn’t need them.

Like the fit-out, the menu at Cafe Bü is minimalist, elegant, and lovely. I had a simple avocado toast, chai, and later a lamington and a coffee because it felt so luxurious to be able to eat my food and drink my tea while it was still hot, and it just felt so good to see blue skies and sun again.
