I've been working on a few ideas in my free time for several years, and I'm also a frequent bar visitor. I live in a central part of a European city that is quite tourist-heavy, and I don't have a problem talking to strangers, whether they're locals or tourists. I never initiate discussions about my hobby projects, but if enough beer is consumed, such discussions are inevitable.
I have a clear impression that you can't get much reasonable feedback this way. Most people just don't know what you're talking about and will either support or dismiss your idea without knowing anything about the topic. They mostly react based on likeness to previous discussions or on a human likability level. Getting feedback this way has never worked for me.

Bringing up a business idea as a conversation topic after getting to know someone over beers is one thing.
This blog post isn't about that, though. It's about ambushing people at a bar and demanding they review your startup idea.

That sounds even worse to me. That needs a very friendly bar to afford to be that annoying. :)
