When it comes to weddings, it can seem like there is nothing new under the sun. Mashed potato bar where you fill up martini glasses with cheddar, chives, and bacon bits? Ethiopian food buffet complemented by buckets of injera on each table, thoroughly confusing the elderly Jewish guests? Karaoke? A Simpsons theme? Done and done (and I mean done). If you can’t provide your guests with an original experience, though, at least you can let them have fun — like by mixing their own drinks!
