  • 10/10 Recommended

    We just left from having our 8-year-old’s birthday party, and I can’t say enough good things—10/10 recommend!

    From the very beginning, their communication was amazing. They answered all of my questions quickly and made the booking process so easy and stress-free.

    The day of the party was even better. The staff was incredibly friendly, attentive, and so great with the kids. They kept everything running smoothly, which meant I could actually relax and enjoy the celebration too (huge win for any parent!)

    Everything was organized, fun, and truly made our child feel so special. You can tell they genuinely care about creating a great experience!

    We will absolutely be back and will recommend this place to everyone we know!

  • Excellent Service

    Brick Brigade hosted my son’s 5th birthday. They were easy to book with, and it was completely hosted other than food/drinks provided by us. They decorated, planned activities, helped transition between activities, cleaned and served. Excellent for this 3rd trimester pregnant mama! We also had a death in the family and had to change dates by one day, and they were flexible and kind about our situation. Also because of the date change, there were way more adult family members than kids, and they made it super fun and my son felt special on his birthday. He didn’t even notice that it wasn’t a lot of kids. Thank you so much! Definitely recommend!

    Very cute and neat find for us on a visit in Forsyth. There were a ton of discontinued sets, as well as special characters available. There were also very reasonably priced build-your-own options. A birthday party here sounds like it would be super fun.

  • Reliable Store

    I stumbled upon Brick Brigade while driving in the area. Wow!! Fantastic location in historic downtown Forsyth right on the square. The building is super cool. The place is loaded with Lego and Cobi bricks. They have hard to find sets and collectibles. They have minifigs and also a dig pile. Sign outfront says they do birthday parties, too. This is a family owned shop and the staff was friendly and very knowledgeable. I wasn't with my kids on this trip, but next time I am near here with them, I will definitely make another stop.
