Gluten-Free and Vegan 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.
Sibby's Cupcakery is a cupcake bakery in downtown San Mateo that says it is peanut-free and tree nut-free. It bakes ten flavors in a gluten-free version and one vegan chocolate cupcake, but says it uses wheat flour and does not recommend its cupcakes for celiac disease. Coconut appears in two signature flavors, so ask the bakery about your needs.
