Who needs a cocktail -- or dessert -- when there's Irish coffee in the house? The hot beverage, a blend of coffee, Irish whiskey and sugar, is usually topped with heavy cream, sometimes whipped.

While the drink is a classic, every bartender has his or her own way of making it. And it can be customized, so if you're worried about not being able to sleep afterward, there's always decaf.

In honor of St. Patrick's Day, you can find three slightly different versions at these Irish restaurants.

FLANAGAN'S PUB

Bartender John Kurtz starts with freshly brewed coffee mixed with a little raw sugar. To that, he adds a shot of Jameson's Irish Whiskey. Then, he tops the whole thing with freshly whipped cream sprinkled with a little more raw sugar. ($6)

At this Irish newcomer, bartender Amy Magee starts with freshly brewed coffee, to which she adds an ounce and a half of Tullamore Dew Irish Whiskey and some sugar. Then, she stirs it all up and tops it with freshly whipped cream. ($8)

O'HARA'S ALE HOUSE

Bartender Michael Feeney offers several versions of Irish coffee at this new Irish gastropub. For the traditional one, he uses freshly brewed coffee, a shot of Jameson's Irish Whiskey and freshly whipped cream infused with Baileys Irish Cream. The "Irish kiss" features Baileys Irish Cream and Kahlua in place of the Jameson's, which, in the "O'Hara's" version, is replaced by a mix of Baileys Irish Cream and Bushmills Irish Whiskey. ($6 each)
