Hi, I host Baltimore Brews and Board Games. A fellow /r/Baltimore poster sent me a message suggesting I post the info over here.
It's the 4th Tuesday of every month at the Windup Space, so the next one is July 23rd. 6-11 pm, no cover. It involves drinking and game playing, as you may guess from the name. I bring a collection of classic and contemporary games, a lot of people bring their own games too. So, you can bring games but you don't have to. All winners get prizes, ranging from shit I picked up at Costco or the dollar store, to free drinks, to gift certificates to local nerdy stores (Alliance Comics Baltimore, Shananigans Toy Shop, Canton Games).
