Yes, there is one in my town. I had a meal there. It was a lot of fun. We ate celery. Unfortunately, the meat had to come from another farm as the proprietors had their hands full trying to grow celery.
I think the idea behind farm to table is not that the owners of the restaurant supply everything they serve themselves but know their suppliers personally, maybe have been to the suppliers farm, and can answer detailed questions about their restaurants supply chain.
These excuses are getting increasingly silly. If you want to know where your food comes from it's not that hard to find out. If you don't, that's your choice.
I don't know what it is like where you live. Where I live, there aren't many farm to table restaurants. I attend plenty of events and end up in situations (e.g., airports) where I have limited control of what I eat. I look forward to a day where cruelty to animals is illegal, so one doesn't have to believe in some free market fix.
