Food carts, trucks, etc.
My sister just went to a wedding where they had a taco truck come at midnight and serve "free" tacos to all the guests for an hour or so. She said this set them back about $600, which, compared to Bay Area caterings costs is a steal.
Even though BF and I are pre-ring, we talk about little wedding stuff all the time. I found out that on the set of The Office they order a cart or truck to come every week, and they once got an In N Out truck! I was totally in love with this idea until the BF nixed what was by then my third cart/truck proposal.
In the event he changes his mind about the food carts, etc., what other ideas do you have for midnight snacks on wheels? The other two he didn't like were popcorn and fresh waffle cones with ice cream.
