"When the retail cafe of the Machine Shop pop-up opened in the beginning of 2022, lines formed out the door instantly. Eager Philadelphians gathered at the Bok Building to get a taste of pastry chef Emily Riddell’s quince kouign amann, twice-baked almond croissants, lemon tarts with toasted meringue, and sourdough breads. Every pastry at Machine Shop is worth the wait. Just get there on the early side — Riddell frequently sells out." - Ernest Owens, Eater Staff
