Final Four Results
Hamilton Tavern5517 Harford Road,  426-1930, hamiltontavern.com Hamilton Tavern's "Crosstown Burger" is made from Roseda Farms beef, comes standard with lettuce, onion, and horseradish cheddar cheese, and features optional additions of bacon and/or a fried egg, and while we're not against an all-out burger experience, this one is so tasty and substantial that you may want to opt out on the cheese and extras to focus on the burger.
Kooper's Tavern1702 Thames St.,  563-5423, kooperstavern.com, @BRGRwagon In Baltimore, the name Kooper's is practically synonymous with burgers. The place epitomizes gourmet gluttony: They deck out their hefty patties—made with Black Angus beef, Wagyu beef, lamb, bison, elk, and more—with roasted garlic cream cheese, Baja slaw, truffle arugula, crab dip, and other drool-worthy toppers.
Mother's Federal Hill Grille1113 S. Charles St.,  244-8686, mothersgrille.com Mother's gets a lot of flak because of its binge-drinking clientele, but the burger options here, concocted by a chef who formulates his own rub for the patties, more than make up for the company. There's a pit beef burger, a hot dog burger, a mushroom gravy burger, and 17 more, including the "Heart Attack"—a beer-battered patty infused with cheddar cheese and deep-fried—which has been featured on the Food Network and NPR.
The Abbey Burger Bistro1041 Marshall St.,  453-9698, abbeyburgerbistro.com With everything from a fried green tomato burger to a lamb burger, and a build-your-own checklist that includes wild boar, kangaroo, elk, bison, and a slew of toppings, this spot is for serious burger innovators everywhere. And it also happens to be a favorite of Orioles center fielder Adam Jones.
