WATERTOWN, Wis. (CBS 58) -- We've all heard of the Bloody Mary cocktail, but at the Uptown Bar in Watertown, they're serving up Mocha Marys to their customers. 

The hard coffee cocktail is perfect for your sweet tooth. 

It's Pabst hard coffee poured over ice with some skewers of donuts and treats. 

The owners came up with the idea after a request from a customer. Since then, it's gone viral on Facebook.

"Our average likes on people reached are about 4-500 per post on Uptown Bar's Facebook page. Within a week and a couple days, now we've reached 892,000 people," said Nicole and Bob Smith. 

The cocktail has even inspired a Mocha Mary drink menu, including the Elvis Mary, White Mary and a Sexy Mary with whipped cream.
