My South Bay/Peninsula Restaurant List


Over the years, enough people have asked me about where I like to eat in the South Bay that I decided to put together a list and make it publicly available. I hope to keep it updated. You might not agree with my choices, and that's fine. You might just have different tastes from mine! I hope that some people will find it as a useful start to exploring the great variety of places to eat "over the hill".


Here is my current list of places to eat in the South Bay and Peninsula
