Pairing breakfast with beer helps to ease a hangover and gives bartenders something to do before dinner aside from pep-talking their taps. Imbibe brews before noon with today's Groupon: for $15, you get $30 worth of American comfort food at Dunlays on the Square.

At Dunlays on the Square, chefs weave American comfort food and grilled favorites into a menu of burgers, seafood, and homestyle entrees as well as a brunch lauded by the Chicago Reader and Centerstage. Diners fight morning fatigue and chase away nightmares of a world without beer by noshing Big Mike's irish breakfast, in which two eggs cozy up with bacon, sausage, a broiled tomato, and cheesy hash browns beside a frosty pint of Guinness ($12). At dinner, barbecued baby-back ribs reign supreme, emitting the fiery aroma of Smoke Daddy barbecue sauce ($12 for a half slab; $21 for a whole slab). Chefs craft popular veggie burgers in-house from a blend of rice, beans, walnuts, soy sauce, and sweet potatoes tinged with a jalapeño mayo ($9.50) spicier than flamenco dancers wearing red-pepper perfume.

Servers lean into breezes on the outdoor patio in warmer months or slide bloody marys made from Smoke Daddy's Smokin' Mary mix and a shot of Guinness ($7.50) down a glossy bar equipped with flat-screen TVs that spew sports. Cozy booths and tables in Dunlays' softly lit dining room foster intimate dinner conversations and private budgetary reviews.
