A Sprinkle Of Info

october, 2020

Once Upon a Sundae was founded 15 years ago this year by AnnMarie- mom of 3- oldest daughter in her 2nd year at Boston University (Go BU Terriers), middle daughter in her first year of high school and son in 1st grade! It’s fair to say AnnMarie can relate to all stages of #momlife!


AnnMarie And Family About

Her experience in the finance world prior to opening Once Upon a Sundae coupled with raising 3 amazing children (along with her beloved husband of 22 years) has much to do with the success of Once Upon a Sundae. All 3 of AnnMarie’s children went to nursery school in RVC and the family remains very active both socially and charitably within RVC and the surrounding towns.

She gets it…parents today desire a clean and unique atmosphere to socialize, to get creative, and to throw the most MEMORABLE celebration at a reasonable price! Come visit us and see why Once Upon a Sundae continues to draw customers from Brooklyn, Queens and both the North and South Shores of Long Island!

AnnMaries as a child

Some of you may recall the name from a Brooklyn landmark luncheonette…the owner is originally from Bay Ridge, Brooklyn and has many fond memories there as a child. Our goal is to create LASTING SWEET MEMORIES for your child to look back on as adults!

Established in 2005 in Oceanside, NY, Once a Sundae relocated to the beautiful village of Rockville Centre, NY in August 2015. Our shop is adorned with whimsical farmhouse decor in a soft, inviting palette complete with a child-size ice cream bar! We offer a family-oriented, community space for kids and families to enjoy all year long. We specialize in unique birthday parties that are perfect for boys and girls ages 1-12! Our magical parties are offered during the week after 4 pm and on Saturdays and Sundays. We offer walk-in open play, craft and make your own sundae sessions Tuesday-Friday. Contact Us Today!
