Face it, unless you had a night so bad that dry toast is an adventure in gastronomy, the best tonic for excessive partying is a quiet, hearty breakfast in a soothing setting. Like Roseville's Pippin's with its tiny, warm caramel rolls. Or the Local with its two-for-one Irish coffees, British sports on the tube, and creamy hash browns. But most times, Northeast's Keegan's Pub fills the bill the best. Sure, the decor is calculatedly quaint (the bar was shipped over in pieces from Ireland and assembled Stateside), but those padded barstools and squishy reproduction couches are terribly kind to hungover bones. The tie-wearing bartenders mix a strong Irish coffee, and intuitively know when to shoot the breeze or leave you the hell alone. They also assemble a Bloody Mary that could be a light meal for Atkins dieters: The drink is topped with a hardboiled egg, a strip of bacon, and enough vegetable garnishes for a salad. If you're still peckish afterward, the menu features an Irish breakfast with bangers and black pudding ($9.95), as well as a nicely made Eggs Benedict ($9.95), in addition to all kinds of lunch-y things. The real piece de resistance, though, is that staple of Army mess halls, creamed chipped beef on toast, a.k.a. S.O.S. Keegan's version sets tender, salty bits of rehydrated beef in an unctuous pale gravy of heavy cream laced with garlic. Dolloped over crisp white toast, paired with a side of fried potatoes, and accompanied by the hair of the dog of your choice, it's an alcohol sponge par excellence.
