The Texas Discovery Gardens now include a new wonderful butterfly conservatory that is basically a rain forest in a three-story greenhouse brimming with exotic butterflies. Elevated walkways allow guests to follow the butterflies all the way up into the tops of the trees. For $200 you can take 40 kids there for a unique and memorable birthday party. The thoughtful folks at the Discovery Gardens provide decorations and have even come up with gender-specific themes: "For the Love of Butterflies" for girls, and for boys, "For the Love of Bugs." You get two hours, an educational gift for your child and the staff does the clean-up. Kids can roam out into the outdoor gardens if the butterflies aren't enough. Two shifts, Saturdays and Sunday. Make reservations.
