Will do this idea, but will use pretty beverage dispensers and maybe even garnish glasses + put out nice straws to match drink/glass. (Mason jars filled with summer drinks. A great idea for outdoor wedding receptions or events.) <--- do thatttt!
Grab some flat stones from your yard (or get the nice ones at a garden supply store), give them a quick cleaning, and write a menu item on each with a white paint pen. You can also use them as place cards or napkin weights on a breezy day.
