The Picnic House’s 4,000-square-foot glass-and-brick-enclosed pavilion features a wood-burning fireplace, hardwood floors, and elegant French doors leading out to a rear balcony. It’s available in eight-hour blocks (five for the event, three for setup) and hosts up to 175. Tables, chairs, an upright piano, and security are included in the $3,500–$5,000 fee—much of which goes back to the park for maintenance and preservation. Catering is additional and limited to a select list of vendors.
