You only have two hands, which makes drinking and eating at the same time difficult. Sure, you can hold a plate in one hand and your beer in the other, but then how do you get to the food? It's hard.
The Go Plate is a brilliant solution to that problem. It's a plate that fits over a bottle, cup or can, allowing you to eat off of your drink. You can get a pack of 42 of the dishwasher-safe plates for $48, which should be plenty.
