Mama Ganache hand-rolls truffles from fairly traded chocolate in a small Monterey Street shopfront, San Luis Obispo's quiet chocolate workshop.
Why locals love it: A family chocolate workshop on upper Monterey Street that most drivers pass at 40 mph on the way to their motel.
Tip: Truffles are made in-house from ethically sourced chocolate; boxes survive a day of wine tasting in the boot.

Nite Creamery freezes ice cream to order with clouds of liquid nitrogen in the Creamery Marketplace, San Luis Obispo's after-dinner science show.
Why locals love it: A liquid nitrogen ice cream counter tucked into the Creamery courtyard, open from 13:00 at weekends and 16:30 on weekdays.
Tip: Each scoop is frozen to order with liquid nitrogen; go after dinner at Bear & The Wren next door.

Del Monte Cafe has cooked for San Luis Obispo's Railroad District since 1981, a family diner in the old workers' quarter by the Amtrak depot.
Why locals love it: A railroad-district diner two blocks from the Amtrak platform that tourists on Higuera Street never find.
Tip: Sunday service stops at 14:00; on weekdays it is one of the few diners serving dinner.

Corazon Cafe pours cafe de olla and plates Latin brunches behind a modest Higuera Street shopfront, San Luis Obispo's quietest great breakfast.
Why locals love it: A family-run Southern Mexican coffee counter squeezed between Higuera Street retail, easy to walk past at brunch hour.
Tip: The cafe de olla, spiced with cinnamon and piloncillo, is the order that sets it apart downtown.

Hungry Mother builds banh mi, po'boys and rice bowls from a scratch kitchen on upper Monterey Street, still San Luis Obispo's best-kept weekday lunch secret.
Why locals love it: A weekday-only banh mi counter in a Monterey Street suite, lunch only at the start of the week and closed every weekend.
Tip: It closes at 15:00 on Mondays and Tuesdays and does not open weekends; plan a weekday visit.
