Considering everyone will come after work, we will make it simple and welcome to just wear business casual. No requirement on color.
The venue has plenty of parking spots. When you drive over and set the destination to be "Brazilian Room" on Google Maps, it will direct you to the entrance of the venue and you can park at the entrance parking lot. If it's full, you also park on the "Anza View Road" behind the venue. Like below, advise to pre-download the map before coming!
Two kind reminders: 1. The venue is located within the Tilden Regional Park and with limited access to internet (wifi is available within the venue). Please make sure you pre-download the map before driving, so you're not lost when you drive over. 2. The park can get a bit chilly at night, though the event will be indoor, but advise to bring an extra layer.
Regional Parks Botanic Garden is right next to the venue if you want to explore around. See this website for more info: https://nativeplants.org/visit/hours-admission. The park closes at 5pm and it's free to public.
