Park Slope Birthday Lunch
For Williamsburg, I would recommend Dressler's for Sunday Brunch as a special occasion place. Also Marlow and Sons but they don't take reservations. For the most special place in Brooklyn half way between Park Slope and Williamsburg, your daughter might love the River Café. They have a $55 brunch on Sunday.
