"Lisa Nguyen started Heyday as a pop-up, pulling inspiration from the broader Asian American culinary lexicon — using a combination of wheat and rice flours, Nguyen would serve doughnuts in flavors like baked ube and coconut sweet corn (a play on the Vietnamese dessert chè bắp). At her counter within the Collective Oregon Eateries food hall, also known as CORE, Nguyen serves airy doughnuts in flavors like passionfruit chocolate or ca phe sua (Vietnamese iced coffee), as well as chewier baked doughnuts, including coconut pandan and the original favorite — baked ube. You’ll also spot Heyday doughnuts at coffee shops like Portland Ca Phe, Electrica, and Less and More." - Rebecca Roland, Nick Townsend, Eater Staff
