I really like this idea that I saw on pinterest. I think I would set them out near the entrance of the reception area. They would be by the board that has the table assignments, instead of having the assignments listed on the toothpicks like in the picture.
I don't imagine everyone would enjoy straight tequila shots, what would be your alcohol pick that would be crowd friendly? So far I've thought jello shots or a fruity something.
ETA: My venue allows shots, wedding is adult only, several bartenders will be on site overlooking the alcohol that is served.
