Once the Earl of Sandwich was given his namesake food, a rash of local monarchs—such as the Duke of Hamburger and Lord Shrimp Salad—coined their own culinary creations. Bite into royal flavors with today's Groupon: for $25, you get two burgers and two draft beers at PubOne in DUMBO, Brooklyn (up to a $50 value).

PubOne sets stomach grills aflame with a creative burger menu bursting with 11 imaginative and innovative burgers. Parading before hungry diners are standouts such as the drunken mushroom burger, which slurs together red-wine-soaked mushrooms, pickled onion, and blue cheese ($14) and can often be found stumbling into neighbors' rose bushes. The mahi-mahi burger reels in a cucumber-dill yogurt topping ($14), and the goat-cheese-stuffed lamb burger with mint ketchup ($14) nestles flavor within flavor like a savory, hooven nesting doll. All burgers are flanked by fresh lettuce, tomato, and red onion and get additional backup from sides of fries, pickle chips, and coleslaw.

Irrigate dry taste bud crops with a healthy selection of draft beers, including Guinness ($6), SixPoint Sweet Action ($7), and Brooklyn Lager ($5). Patrons may savor sports on PubOne's TV or simply breathe in the friendly, casual atmosphere with a friend or malnourished burger enthusiast.
