Very, very cool. I've seen these a bunch of places before and always thought they were such a good idea.

No more fumbling to carry your food and beverages at a party. With the Twelve Piece Wine and Dine Buffet Set, your wine glass fits neatly into the grove of your plate. No spills, no worries. (via Just Wine Racks)

They're comfortable to hold while you eat and drink at a cocktail party... you don't have to put down your drink just so you can eat your crab cakes. Great for people with alcohol separation anxiety. (via Cookware Essentials)

This is such a great idea for those who love to entertain! You can serve wine and food to guest and not have to worry about how they are going to balance holding it. These are great if you have limited table space, or if you simple want to make life easier for your guests.
