About Neptune

Baking for the harbor community

Neptune isn't just a bakery — it's a corner of Vallejo where the smell of fresh bread hits you before you even open the door. We started with a simple belief: that great food shouldn't require a fancy address.

Located right on Harbor Way, we combine an artisan bakery with a curated grocery selection. From our signature sourdough loaves to locally sourced pantry staples, everything we offer is chosen with the same care we put into our dough.

Our Story

Built on the belief that good food brings people together

Neptune started as a passion project — a desire to bring real, honest baking to a neighborhood that deserved it. We chose Harbor Way because this is where we live, where our kids go to school, and where we want our community to thrive.

Every loaf we bake, every item we stock, and every smile we share at the counter is part of the same commitment: making 42 Harbor Way the kind of place you're glad to drive past — and even gladder to pull into.
