The first good think I did was right a preview about the restaurant opening in this blog on Blogger. That was good in two ways. First the owner of my borothers restaurant was not sure he wanted to pay for a site. We showed he needed one buy the fact that my one post got position 1 on Google for 'the black rat winchester' in a few days. This showed that no one was going to find them without my page and I even got personal emails of people trying to book dinner. So found that that works as a good example but I guess it was because we have an open market on the name. Everything else is for real rats or a black rat drink in america.
So even though I think The Black Rat is a bad name for a restaurant but for SEO it is kind of good as there is no real competition on the name. Unlike say "The Royal Hotel" or something common.
This ranked page still is the top referer after google. And when they had a website up I linked this ranked page. Even this related post will help the rankings, though it would be better on food not SEM activity.
