The Guide: Kids’ Birthday Party Venues in Somerset County, NJ
How to Use This Guide
This guide lists places in Somerset County that publish a children’s birthday party package on their own website — a package name, a price, or a party page. Each row shows the venue, its town, what kind of place it is, which age groups its published information covers, the lowest published party price, whether the venue describes a private room, how many guests the published package covers, and what the venue says about food.
The three age columns are ticked only from what a venue publishes: a stated age range, a minimum age, or a party product aimed at that age group. A venue that publishes no age gets no tick and the Ages cell reads Not published. A tick means the venue’s own words cover that age group; a blank means they do not say. Prices are the lowest figure a venue publishes for a children’s party and change often, so treat them as a starting point and confirm when booking.
Below the Somerset County table is a second table of venues over the county line, within a 25-mile drive of Hillsborough, that pass the same test. The second table is sorted alphabetically, not by distance. Venues that take parties only by request, with nothing published, are not listed.
About This Guide
This guide is produced by Garden State Circle. Venues appear here because they meet the criteria described above — a children’s birthday party package published on the venue’s own website, in Somerset County for the first table and within a 25-mile drive over the county line for the second, and a website of its own. That is a test, not a judgment, and it is the only route onto this page. No business can pay to be included in this guide, to be listed higher, or to change what the table says about it. Businesses are listed alphabetically, and every detail in the table was verified against each business’s own website or Google Business Profile in October 2026.
Everything under the heading that begins this guide is governed by the rules above, on every guide we publish. Garden State Circle is supported by the businesses that participate in it. Participation pays for our ongoing work: keeping a business’s entry accurate, re-checking its record, and publishing a page of its own details that the business maintains. There is no paid placement in this guide. Participation does not buy a place here, a position here, or anything the comparison table says. Where a row carries a verification date, that is when we last checked that business’s record ourselves. A row without one has not been checked recently — that is a fact about our work, not about the business.
Garden State Circle is published in New Jersey by Tiffany and Jake Slowinski and covers Somerset County. Contact the publisher at jake@gardenstatecircle.com. How every guide is made, in one place: how every guide is made.

Towns, ages, prices, room, guest and food wording are each venue’s own, taken from its own website in October 2026. Not published means the source we read does not say. A tick in an age column means the venue’s published information covers that age group.
Common Questions
Why are some age columns blank?
A blank means the venue does not publish an age for that group. Many venues write “all ages” or nothing at all; neither earns a tick. Call the venue if the age range matters for your group.
Why is a venue I know not listed?
Either it publishes no children’s party package on its own website — parties by request only — or it has no website of its own, or it is more than 25 miles from Hillsborough. Venues that read as closed on their Google listing are also left off. If a venue has since published a package, write to us and we will check it.
Do the prices include everything?
No. The price shown is the lowest a venue publishes for a children’s party, usually for a set number of children. Extra guests, food add-ons, themes, deposits and tax are typically extra; the Max guests and Food cells show what the venue says about that.
What does “private room” mean here?
It is the venue’s own description of where your party sits — a private room, a reserved table in an open play area, the whole facility. Where a venue describes nothing, the cell reads Not published.
Are chains and franchises included?
Yes, on the same test as everyone else. The Type cell says (chain) or (franchise) where the venue’s own website shows it.

To correct an entry, email the publisher with the venue’s name and a link to the page on its own website that shows the change. We check it and update the row.
