The Buttery opens Bryn Mawr café with sourdough at the center

Bryn Mawr is about to get a bigger, bread-forward version of The Buttery, and sourdough sits at the center of the move. The Main Line bakery-café is set to open its third location on Saturday, June 13, at 836 W. Lancaster Avenue, bringing the brand’s all-day menu, seasonal kitchen and sourdough program into a neighborhood that has not had this exact setup before.

What makes this opening matter for sourdough regulars is the way the bread program is being used as the engine, not the garnish. The Buttery is keeping pastries, sourdough loaves, coffee, tea and grab-and-go items in play even after lunch service ends, so the new shop can work as both a sit-down café and a place to leave with bread in hand. That gives Bryn Mawr something different from a standard suburban breakfast stop: a place where the loaf itself is part of the daily rhythm, from morning coffee through the late afternoon.

The new dining room also gives the concept more room to breathe than the existing outposts in Malvern and Ardmore. With 82 indoor seats and a schedule that runs from morning through late afternoon, the Bryn Mawr café is built to absorb the kind of steady breakfast and lunch traffic that keeps a bakery busy, while still leaving space for people who just want to pick up sourdough and go. For a brand that already centers breakfast, lunch, pastries, sourdough and coffee, the expansion looks less like a duplicate and more like a larger stage for the same core idea.

In practical terms, that is the appeal of the Bryn Mawr opening. It extends The Buttery’s reach on the Main Line, but it also makes the bread program easier to access in a part of the neighborhood where an all-day café with serious sourdough is a real addition, not just another opening.
