You don't say which part of Seattle you live in, so it makes it difficult to recommend any locations. Because it's on a Friday night and it's extremely short notice for any of the invitees, I suggest, to minimize your headaches and your daughter's heartaches that you select a restaurant, like an Olive Garden, Red Robin or have a bowling party at Acme Bowling in Tukwila or another alley close by. Bowling has gained a renewed sense of popularity with kids, as it's one of the venues for grad night parties... it's not our parents' bowling alley, lots of music, lights, good food, and fun. And seeing as how it's on the Friday night you'll be running competition with that evening's football game. And it's the night before Halloween, how many Halloween parties are there that night? Again, by having it at a restaurant or the bowling alley... you'll save yourself the headaches. Most kids go to these venue parties with the expectation that they'll be paying their own way, so it's up to you as to how much you want to pay towards the bill. At Acme, give them a call, I believe they have a package deal. If you want to celebrate with family, have a buffet at home. Have a great time!
