If there's one element of your wedding that your guests will remember it's the food. Along with the location, décor style and music, the catering will define the event. Cuisine gives you the opportunity to really show off your creativity; and if successful, will leave an ever-lasting impression on your guests.
So. Unless your bride has a bad feeling about this--and make sure she's being 100% honest--use your folks, pocket the cash, and go spend it on something worthwhile. Like... booze.
