how do find out who owns franchise fast food establishments and who is owners of small food establishments?

Have been searching for owners info via online for state of California. Been checking search engines and checked BBB and not listed, and food is not apart of consumer affairs. Any suggestions?

needtoknow makes a good point. My preferred m.o. (besides contacting the local Chamber of Commerce) is to go to the restaurant in question. If it’s a conscious owner, he/she will likely be working there, and will likely stand out as being the friendliest, most social, etc. Granted, this is a bit altruistic as many restaurant owners are not people people, or do not care enough to actually be in the store. If that fails, just ask a manager, they should know.
