Yes! Birthday party pricing only applies to parties booked in advance, but if there are tables available, we are happy to accomodate walk-in birthday parties at regular park pricing. No minimum number of guests required. First come, first serve. You can bring a birthday cake or dessert and table settings and decorations, but no other outside food or drink is allowed. If you need to keep something cold, we would be happy to put it in our refrigerator.
