One of the biggest trends out there right now is arranging for a food truck to park outside of your reception site, offering guests a surprise last taste of the night. It could be Cuban sandwiches, pulled pork sliders, mini burgers, even hot dogs or cupcakes. We have some spectacular food truck enterprises here in New Jersey, offering food that would make Top Chef contestants envious. (For more, see “Rev Up Your Reception Menu” or “Hot Diggity Dogs.”)

But before you book that food truck, be sure to ask your reception site manager if it’s OK first. I’ve heard from a number of brides and grooms who put down a deposit on a food truck, and then had to cancel (losing all that money!) when the reception site says, “No way, not on our driveway.”

Each venue has a right to make its own rules, and it might be more a matter of insurance than not wanting a branded truck on their grounds.

And imagine how awful it would be to book the food truck, pay for it in full and then walk outside your reception to find it not there. The site managers turned them away. That, too, has happened.

And here’s another warning: Don’t book a food truck for your at-home rehearsal dinner or wedding weekend party unless you have a very long driveway where it can park. Otherwise, everyone in the neighborhood could walk up to it and grab a slider. Talk to your food truck operator about how they handle at-home parties, which permits you may need and if they get them for you, then call your town hall about the need for a food truck permit as well. Even if the food truck company says they’ll handle permissions, your town might have a weird ordinance they don’t know about, so it’s best, as my Aisle Files tip: to call the town hall and ask about food truck permissions before you book.

And you may want to consider making a food truck privacy plan! If your wedding is taking place in a public location, like a park or beach, the food truck you hired to await your departing guests could be swamped by strangers who don’t realize this truck has been privately arranged for your wedding. So put up signs—and even consider the idea of giving your guests wristbands so that they can be served at the truck. Glow bracelets could work as well.
