I haven't been there yet, but here is a link to the brewery's page here on BA, and it has a good number of Beer reviews and 4 Place reviews with the latest being last August. http://www.beeradvocate.com/beer/profile/39159/
Worth the trip in my opinion. I haven't been since the summer but the few brews I tried then were solid...Milk Goblin was the one that stuck out in my mind (low ABV milk stout). My only complaint is that they didn't offer flights when I stopped by. I wanted to try more of their taps but that policy hindered it. I probably wouldn't mind so much if I made it into the city more often but I don't. Their food is good, too but they don't have a huge menu. If you're looking for a good place to grab a bite nearby, you have to check out Mudgie's Deli....it's a 1-2 minute walk up the street from Batch. Think kick-ass sandwhich shop where you can order beer, wine and mead. Lastly, Brew Detroit is very close as well to both Mudgie's and Batch. They usually have a few different taps of stuff they make and its in a different atmosphere. But, I didn't find the quality as good as Batch when I went.
