I'm guessing this is an evening affair since you said mock martinis. I really like that idea. Can you get them to match? Well I know you can, so you should do this.
Food...Well I'm planning an April wedding and like you we're short on cash. And where I want my reception is pretty much our budget. I REALLY want this place. Anyhow...we're going no more then 7 bucks/head for a picnic type theme by Farm Fresh. They actually have good prices and decent food. Any of those in the area? Um to also save money we're thinking of doing a brunch. The earlier the meal, the cheaper it gets! LOL.
Otherwise sounds like deli platters and cheese plates are the way to go.
