Nut-free, Peanut-Free, and Soy-Free are on the menu, but the same kitchen also prepares what you avoid, so cross-contamination is possible. Tell staff what you react to, and ask how your dish is prepared before you order.
Petunia's Pies & Pastries is a downtown Portland bakery cafe that says it was the city's first entirely gluten-free and vegan bakery. Beside cupcakes, doughnuts, pies and cookies it serves breakfast sandwiches, burgers and pizza, and it says the savoury side is made without soy or nuts apart from coconut. Sweets vary by day and can contain peanut, nuts or soy, so ask the bakery, it has the final word.
