My husband and I will be in the Bay area starting Friday. We had planned to spend 3 days in the Carmel area, 3 days in Yountville & 3 days in San Francisco. Unfortunately, work has reared it's ugly head & we have to cut the trip short. Since we have been to San Francisco before, we are cutting that part of the trip to 1 short day. We will leave Yountville on Wednesday & catch a plane back to Austin at 5:30pm out of SFO. Since dim sum is beyond bad in Austin, we wanted to check out Yank Sing. Can we park at the Ferry Building for several hours & walk there or is there another dim sum place easy to drive to that would be better? We don't relish driving alot in the city.
