- Israeli : Oren’s Hummus (various Peninsula locations, I like their hummus, don’t know about other stuff)
- Mexico City: Los Carnalitos (al pastor tacos; Redwood City food truck; link is Hayward brick and mortar but same stuff)
- Sichuan: Royal Feast (Millbrae; classic dishes, pan fried fish cakes ); Chef Zhao Bistro
- Jiaozi (boiled dumplings) : Tasty Place
- Hunan : Wonderful (Millbrae)
- Cooking Papa
I haven’t been to these in a few years:
- Romolo’s Cannoli (San Mateo)
- La Casita Chilanga on Middlefield, especially the tesorito torta.
- The Refuge (San Carlos; pastrami)
- Copenhagen Bakery (Burlingame; Danish), not in the same league as Alexander’s Patisserie, but they have some almond based desserts you won’t see elsewhere (I stopped eating marzipan, almond extract, etc. so they’re a minefield for me)
FWIW, I asked a similar question six years ago on CH. Way outdated, but might give some other ideas
