"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." - Nick Townsend, Eater Staff
"Before Nguyen opened her Southeast Portland doughnut shop, she participated in pop-ups with Le; Dam developed a house roast for Heyday’s shop, as well." - Brooke Jackson-Glidden
"Another fan favorite of the current mochi donut craze in Portland is HeyDay, which started in May 2020 as a pop-up before getting a home base stall at the Collective Oregon Eateries (CORE) Food Hall along 82nd Ave in Southeast Portland in 2023." - ByZoe Baillargeon
"HeyDay has teamed up with Salt & Straw to raise funds, offering a pandan cream soda and waffle specials with proceeds going to the Maui Relief Fund." - Janey Wong
"Lisa Nguyen’s popular HeyDay Donuts will have a brick and mortar location in 2023. I’m so excited that she’ll be able to expand her offerings." - Eater Staff
