What's the best place for a bachelorette party with a *sighs and rolls eyes* Star Wars theme?

Yes, it's true. Star Wars. The bride is Princess Lay-a (yes, that's how she wants to spell it), the bridesmaids and I are gonna be dressed in variations of Princess Leia. For instance, my hair will be in braids with it in a bun on the crown of my head. We're all gonna be in y variations of Leia's clothes. Anyway, the bridesmaids don't want to go out in public dressed like that, but I don't want to offend my best friend. I have a friend that owns a restaurant (he is not a friend or even an acquaintance of the bride) who is willing to close his restaurant for a couple of hours so we can have the party in public without anyone feeling embarred. The problem is that I'm not sure that will be enough for the bride. I have no shame. So, I'm not worried about me being embarred because I don't get embarred easily. Should we go to the restaurant while it's closed, while it's open, a different public place or someone's residence? I want the bride to have a good time, but if everyone...
