I attended Shacklands' Grand Opening Event back in January 2017 and I've been to the Brewery several times since then; I visited there a couple of times earlier this year during Beer Fests that they were a part of in their parking lot which involved 2 or 3 other Breweries, and last Sat. I made my most recent visit during a Brewpub Crawl with a social Group.
The Brewery is long and narrow, and you can barely extend your gaze anywhere within without catching sight of an artifact or relic from the 1980's, or 70's or even further back. You can purchase either a single beer or a flight of 4 which I did when I 1st visited in Jan. The service at their bar is quite friendly and the venue's Staff quite willing to describe their beers on offer in great detail. I should also mention that they have a piano toward the back, a pinball machine which you can play for free and sometimes live bands when they have special Events.
