Birthday Party Venues in Mosman

Choosing the Right Birthday Party Venue

Harbour water frames most of the birthday rooms on this peninsula. Around The Spit, Ormeggio at The Spit, Chiosco by Ormeggio, Function Room @ The Boathouse at the Spit and Bluebird Room & Deck @ St Siandra all sit at the edge of Middle Harbour, while Balmoral Beach has two dining rooms on The Esplanade and Mosman Rowers looks over Mosman Bay.

Away from the water, Hotel Mosman on Military Road and The Buena at 76 Middle Head Rd handle the pub end of things, and Gili Rooftop @ Taronga Zoo puts a party on the roof of the zoo's events building on Bradleys Head Road.

Matching the birthday to the room:

A long family lunch for a 70th: First Floor Dining Room @ Pasture of Balmoral seats up to 42 at long tables above Balmoral Beach, with a three-course sharing menu from $85 per person.
Dinner for the inner circle: The Good Room @ Bathers' Pavilion seats 16 at one table or 22 across two, looking over Balmoral Beach towards Sydney Heads, from $125 per person.
A 30th that starts with drinks on the sand: Bluebird Room & Deck @ St Siandra on Lower Parriwi Road has its own entrance, bar and a deck over the beach for 85 on their feet; canapé packages begin from $60 per person.
A 40th with the city lights behind the cake: Gili Rooftop @ Taronga Zoo holds 80 cocktail-style or 60 seated, with a circular terrace facing the Harbour Bridge and skyline.
A relaxed pub party: The Buena's Blue Lane can be curtained off for about 70 standing, and canapés there begin from $45 per person, while Hotel Mosman's function managers plan canapé and menu options for 20 to 50.

Big milestones with a long guest list and a dancefloor point to Function Room @ The Boathouse at the Spit: 450 for cocktails or 300 seated, from $195 per person, and operable walls shrink the room when the crowd is smaller.

With exclusive use, Ormeggio at The Spit lets a DJ play amplified music to 10:30pm, and a playlist of your own can keep going through the house speakers; the whole restaurant holds 140 for canapés, from $119 per person.
The Boathouse room comes with a microphone, a sound system and a dance floor, so the toast and the first song of the night need no hired gear.
Bluebird has screens, AV and Wi-Fi for a birthday slideshow, and its evening events finish at 11pm.
The Buena provides a TV connection for photos, but its function areas don't allow microphones or AV equipment, so plan speeches without a mic.

Guest lists, drinks and spending

Chiosco by Ormeggio sits on the jetty beside Ormeggio and takes 90 seated or 110 with canapés on exclusive hire, with sharing feasts from $89 per person and BYO wine allowed.
Mosman Rowers at 3 Centenary Drive has three rooms over three levels; the Rowers Café holds 110 seated or 180 standing, and groups of up to 30 can book share-style dining with a cash bar, tab or package.
Pasture of Balmoral charges no room fee for 30 or more adults, though BYO isn't allowed.
Hotel Mosman's upstairs level, The Upper Duck, has a balcony over the Boronia House gardens and is for over-18s only, which matters if younger guests are coming.
