There is a small parking lot at the venue so it is first come first serve. There are other parking lots at the park that you can walk from. Here is the link to the map (https://www.ebparks.org/civicax/filebank/blobdload.aspx?BlobID=24417). Carpooling is recommended or using ride share apps.
If you are taking BART, Downtown Berkeley is the closest stop. You can take a ride share app from there.
It is cocktail attire.
We are wearing Navy and Olive Green, while our wedding party is wearing fog.
