As with almost everything associated with the wedding - the invitations, the flowers, the centerpieces, the keepsakes, and so on - the drink tokens used are often customized. They will be designed to fit the style of the wedding and will almost always include the names of the bride and groom, and may even include a picture.
So, if the custom wedding poker chips are turned in for drinks and kept with the bartender, how are these memorable? This is simple. As with most open bars, make the tokens redeemable for only a certain amount of time. Once they are not redeemable, thus not worth a drink, they can then be distributed as keepsakes. Custom tokens are the best choice for newlyweds that want their guests to have something to remember the day.
