TLDR: Small, but good selection of craft beer in Dekalb that you can bring with you to go around the food hall.
With all of the good food available at Dekalb, you're probably going to need a drink to wash it all down. If want that drink to a great craft beer, you should hit up Craft & Carry. The place is pretty small - it just has enough room for the fridge of cans and bottles, as well as the taps behind the cashier, but you can bring any drink to go as you walk around Dekalb.
The selection of bottles and cans seemed to be pretty impressive, even for the craft beer nerd. In case the beers on tap aren't that interesting to you, their bottles and cans seem like a great alternative. However, I think the selection of drafts they have, while not the most extensive, is still very solid.

I think they do a great job of having local breweries from around New York and NJ represented in their tap lists. Since I am not from nor do I live in Brooklyn, I really liked that the draft list included Grimm and KCBC. The prices are on the higher end, but are comparable to a bar - you'll probably pay 8-10 bucks per pint.
Service was great and they'll answer any questions you have about the beers they have on tap. It's a great option for craft beer in Dekalb!
