I just read a review of Capone's at 221 North 9th Street, this place sounds good:
"It never hurts to have a gimmick, and that's especially true when you're running a joint on the bar-infested streets of Williamsburg, Brooklyn. One place to have confronted this problem head-on is Capone's, which hands out free 10-inch or so cheese pizzas the way most places serve bar napkins -- one per drink. Made fresh and with a good, chewy crust, the pies easily surpass many of the often plasticky slices sold for $1.75 in this fair city. (If you want a topping, they'll charge you $2 for the first one, and $1 after that.)"
Here is the official website:
It looks very hipster friendly too:
