In lieu of buns, Duffy's Irish Restaurant & Pub's Monster Burger earns its name by piling bacon, grilled onions, and a half-pound burger between two grilled cheese sandwiches. The Washington Post profiled the beastly eat and its “calories-be-damned goodness” in its This Thing You Should Try series. Those with tamer appetites assemble less daunting burgers with a beef or homemade black bean patty served on a white or whole grain Kaiser roll. Along with burgers, Duffy's culinary team crafts casual dishes such as mushrooms fried in peanut oil, vegan pasta tossed with homemade tomato sauce, and seven wing varieties voted the city's best in 2012 by readers of Washington City Paper.

Along with the menu of daily grub, Duffy's staff supplies discounted drinks and quesadillas at weekday happy hours and hosts brain-teasing pub trivia challenges every Wednesday night. 12 flat-screen TVs throughout the bar stay tuned to the latest Florida Gators and Green Bay Packers games, a more thrilling alternative to watching looped footage of an actual gator attacking a defenseless cheese wheel. In addition to front of the house entertainment, Duffy's accommodates private soirees with a back room equipped with more flat-screens, skeeball, darts, and an internet jukebox.
