Seven Heaven Street Fair is a giant street fair (over 15 blocks worth) with over 500 vendors and a myriad of things to do. Take your Dad on a leisurely stroll through Park Slope and show him the wonder of a well-planned street fair. Perfect for all ages, from kids to people with grandkids, and if you're bored you can always sneak off to one of 7th (or 5th!) Ave's many bars for a chin wag with the old man.
