Dress Outlets In San Francisco

My questions to do with Sweet 16 parties?
Okay, so instead of having a big party, I want to take some friends with me to San Francisco to Tiffany & Co. and dining out. I'm going to Tiffany & Co., because it's my birthday gift that allows me to select something for my present:. Questions 1) What type of gift bag or party favor I have to represent Tiffany's and such? 2) What restaurant is a good place for us to go to my birthday dinner? I want to be able to wear (such as prom dresses, super luxurious anything) without looking out of place. 3) How costly limo services? I was thinking maybe to rent a limo to take us to the city. Any good service in the Bay Area you can imagine? Any help is loved! Please and thanks.
