Birthday Party Reviews


My son had a wonderful time on his birthday! He was very happy to be able to build a super hero city with his friends (with lots of jails for villains)! Stephen and John are great with kids and very professional. They did all the setup and cleaning, it was minimum work for me. I also liked
how easy it was to plan it, as I have a full time job, so I really appreciate the stress free planning!


My son celebrated his 7 year birthday in Kidizens at Los Altos location and when I asked my birthday boy which part of the party he likes more – he said “All!!” 🙂

I would rate the party a 10/10, none of the kids or their parents wanted to leave. We would recommend it to anyone willing to hear! We found the booking process pretty simple and everything was easy. We did not have any suggestions for improvement , we thought it went off so well.
Thanks again for making our evening special.


She had a blast and it seems like everyone did- thanks so much for your great facilitation!


My son LOVED his party and all his friends said it was the best party ever.

It was a great experience today at Kidizens. I would definitely recommend your place to my friends. I actually saw today one of the parents so impressed by the place that she texted her friend right away to tell her about booking a b-day party.

10, I would recommend Kidizens birthday parties for birthday kids and guests who love legos. I already told about Kidizens to couple of friends.
I like that the place is spacious and very organized and we got the entire place just for our party. There is a nice big party table. Staff are friendly and helpful. Staff manage the party and clean up after so host parents can relax and enjoy. You guys really made our life easier! The booking process went smoothly. Very responsive.


Now experience the creativity, satisfaction and excitement of building a LEGO city on your special day – the Kidizens way!!

At a Birthday party hosted at Kidizens your child can be the Mayor of a city, a ninja, space crusader, a medieval knight in shining armor or a superhero! Just let your imagination take you on a guided discovery through a LEGO universe…. It is truly an exciting and unique way to mark a memorable birthday, especially for all the LEGO-lovers!

It’s LEGO Birthday Fun For All Ages

When your child hosts a birthday party at Kidizens, it isn’t just a day of celebration, it is a jam-packed day of creativity and excitement. During the party, the birthday child and his/her friends can build an entire LEGO city while role-playing and taking important decisions, immerse themselves in space or Star Wars era or choose from a number of popular LEGO themes. By the end of the party the children create something of which they can truly be proud. We provide a theme-based, countless LEGO inventory, a creative environment supervised by our birthday party coordinator and endless fun!

We now offer birthday parties for different age groups (from ages 5 to 12) at our locations in Los Altos and Belmont. We offer many kinds of parties with varied themes (the theme could vary depending upon the Birthday child’s interests and age, as well as total number of children attending). We often tweak the theme to customize it your child’s passion and to make his/her experience unique. Our party coordinator will supervise and guide all the building activities. You bring your own party supplies, cake, food and decorations. We have mini-figures, candies or small LEGO sets to purchase as party favors.
