We'd love to meet you and hear what you'd like to see on the shelves. Thank you for supporting a small bakery. We can't wait to welcome you.

DeepSeek V4.1 Flash
Passed: Graded 5.0 of 5 on average (lowest 5).
Some news we've been sitting on for a while: Crumb & Co. is opening a second shop, in Leeds, on 14 November. We started six years ago with one oven, one counter and a lot of very early mornings. The idea was simple — good bread, made slowly, sold to people who'd walk a bit out of their way for it. That we get to do it in a second place still feels a little unreal. The new shop will have the same loaves, the same pastries, the same slightly chaotic Saturday mornings. There's more seating, and a window that actually gets sun. To say thank you, coffee is free all day on opening day. No catch, no app, no code — just come in and we'll make you one. We'd love to see you there. Thank you for getting us this far. — The Crumb & Co. team
