I have not been yet... I really need to. Its a separate location from Epic Brewery that is no state st though. I think this took over for the Annex or something like that. Its called Black Sheep at Epic Brewing.

The brewery is still on state st. I go to that one every now and then because they have a beer I want to try. But I agree that I dont like their setup and I generally dont like the employees. Epic Beer is meh to me as well and very overpriced. Some of them are good but its lower on my favorite breweries list.
All these new breweries opening are really great. I love driving around Friday afternoon to Red Rock, Uintah, Proper, Mountain West Cider, Fisher and ROHA and grabbing a couple beers from each for get together s with friends.
Have you tried ROHA yet? This place makes pretty simple beers that are really well made.
I am excited for Kiitos and Toasted Barrel to open up. Kiitos is supposed to be a more eco friendly high tech way of brewing. Toasted Barrel is going to focus on Sour Beers and Barrel aged beers.
