A small, and great team from Salesforce.com office in San Francisco wanted to do a Sushi Class team building event. They had no budget to rent a venue (it's quite expensive to rent on in the city right now - over $1,000 per event!). So what did they do? We did a class at a resident lounge in a condo one of the team members live in.
It's quite a space. Large enough to host 30 people class easily. Fully equipped kitchen with glass and tableware.
Best of all, it was free (only to residents)!
If your co-worker lives in one of these buildings with a community room like this to host your next team building event, we are there!
