Caveat: I am more familiar with the eats around the southern tip of the Peninsula than the rest of the Peninsula.
Ramen Nagi in Palo Alto
Xiao long baos at Panda Dumpling in San Carlos
Kemuri for Japanese in Redwood City
Madamoiselle Collete for French pastries in Menlo Park
Just buy some freshly wrapped and not-yet-frozen dumpling at Dumpling City in Palo Alto, bring them home, and boil them. They have a B&M restaurant- Dumpling Garden in Mountain View, but I haven’t been.
Tai Pan for dimsum if you are that far south. My last experience was poor but the meals before that were good. There was a positive report after my poor meal. I am not familiar with dimsums around SSF/ Millbrae, etc.
Napoletana Pizzeria in Mountain View for neapolitan pizzas.
I am not aware of any real good Vietnamese in this stretch of the Peninsula.
