Birthday Party Planning Questions
How much advance notice do you need?
We recommend 3-4 weeks for optimal flexibility. We can often accommodate shorter notice for smaller celebrations (2-3 weeks), so contact us early with your vision.
Can we bring our own birthday cake?
Yes. Most venues limit cake size or charge cutting fees—we’re flexible. Just let us know the size and any special requirements (candles, refrigeration, serving style) and we’ll handle it beautifully.
Do you have singing staff or special birthday surprises?
We can coordinate special surprise moments. While we don’t have a “happy birthday” singing tradition, we excel at coordinating dessert presentations, champagne toasts, and meaningful celebration moments.
How flexible are you with dietary restrictions?
Very. Vegetarian, vegan, gluten-free, allergen concerns—our chef accommodates all requirements. Share dietary needs in advance and we’ll create premium dishes tailored to your guest list.
Can we do decorations or special setups?
Absolutely. We welcome decorations, special seating arrangements, photo areas, and custom setups. Include your vision and we’ll provide suggestions based on what we’ve seen work beautifully at other celebrations.
