Where Is The Best Place For A Birthday Party?

My son Grant had the chance to go o a birthday party held at a local bounce house. Grant is 3 1/2 and this seemed to be the best place for a birthday party for kids his age. After a little time in the party room with pizza ,drinks ,cake and then presents, the kids then went into the room with some bounce houses and a trampoline, as well as a pit full of foam to jump in.

The thing that surprised me the most is that most of the kids at the party were ready to go home before the time that they could jump was up. I guess they used up all of the energy that was fueled by the sugar they had in the party room.  What do you think is the best place for your young kids to have a birthday party?
