What are some great Golden Birthday ideas and websites where I can get info. on the Golden event (mid 20's age

I would like some help finding websites with decorations and gifts for guest for a Golden Birthday. The guest of honor will be turning 26 and most attendees will older. Will be serving lemon drops and lumpia (sp?), California rolls, lettuce wraps. Any ideas would be great concerning decorations as well. Black, white and champagne are the colors.
