I walked up to Surly around 5 last year (granted it was raining hard) and had no wait. None. Their special tapping and regular side were empty. So I had a glass of Darkness and chatted them up a minute and then tried two of their anniversary ales. I don't think the craft beer scene has changed that much in the past year that interactions like that won't happen again this year. BTW, there are plenty of casuals there who don't care/know about the breweries. They just wanna drink a ton of beer.
