21819 Plummer St Chatsworth, CA91311 (252) 543-9723
Open to the public every Saturday 9am-4pm for free play.
So this Saturday, and possibly quite a few more, you could play some free arcade games, but that's Saturday only. The rest of the week this place rents and sells arcade machines. So maybe try one out and rent it for the office for a month.
This deal might only last for a short time after this is written 11/20/14, so check their Facebook or Twitter before going.
