I went to Black Page a few times, since I live quite close. The site itself is fantastic. You think you're in the middle of the forest, lots of trees and no street noise. The seating indoor and outdoor is very well done. The beer was decent enough and I liked their taco vendor. So what's the issue?
I suspect they were highly in debt prior to opening. I'm pretty sure they had leased that land for a few years before opening, so that's sunk cost. The start-up costs had to be enormous as the building there was a worn-out shell before they re-did it. Plus they needed better marketing. I've followed them in social media and they hardly ever made a post. I don't think they had running clubs, weekly yoga, cornhole tournaments, etc. to get people in there. They needed big signage on N.Main to get pre- and post-concert people in there along with average people driving on the street. I'm not sure how many local neighborhood customers they got, but you'd think if they catered to the locals that they'd have a built-in base of regulars. The other near-northside breweries (Bad Astronaut, Gristworx, St. Arnolds) aren't really super close and a bit of a convoluted drive getting over to those places. The last couple times I was in there I saw the owner/manager just typing on his laptop and not engaging with customers - another issue.
Sad to see them go.
