* Ads are clearly marked.
* Google, please don't take away the near-me recommendations.
* Google, please don't take away the map.
* Google, the wikipedia-like excerpt is helpful; please don't stop doing that. If I wanted to wikipedia the article, I would have asked wikipedia (or "!w pizza" with my browser shortcut).
I don't see any adds for that search result, though the results are now tainted by news articles about that ad and that particular search.
Just to derail the conspiracy train, when I try other searches of the same type, such as "oldest bar in philadephia", I get no ads as well. I would not expect ads for a search that unique.
I also don't get any if I search for nipplegate, for example.
You see, those ads depend on the used search terms. If no one bids on those words, you won't see any ads.
