Casita Colibrí Bakery in Chula Vista's Escaya Village operates a gluten-free bakery concept from 1963 Avenida Escaya in the Otay Ranch area of the 91913 zip code. The bakery builds its menu around gluten-free flour blends and alternative grain formulations, pairing with the specialty coffee program at Donny's Cafe for a dietary-restriction-conscious breakfast combination in eastern Chula Vista. Founded by Rosalba Bustillos, the bakery targets the growing segment of Chula Vista residents managing celiac disease and gluten sensitivity with baked goods that replicate conventional textures. The Escaya Village location places the bakery within the Otay Ranch residential corridor, serving the event and celebration market through dessert builds compatible with venues such as Gather SD. Each gluten-free recipe undergoes cross-contamination controls including dedicated prep surfaces, separate storage bins, and batch-tested flour blends to maintain below-20-ppm gluten thresholds per FDA labeling standards.
