Since November, Nage executive chef Dwayne Motley has been serving up to five off-the-menu burgers every Monday night during the Dupont restaurant's new "Burger Monday" promotion.

The latest beef-and-bun purveyor set to open up shop in the District is Bareburger, who Eater reports is planning for a June debut in the former Cosi space on R St. in Dupont.

Yesterday we got news that Smashburger in Dupont shut up shop barely a year after opening and now today, Eater has word that Black & Orange has become yet another burger slinger of the past.

Fried pickled jalapeños, fried shallots and cheese sauce. On a hot dog. Like we needed another reason to hit up Shake Shack (or refill our Lipitor prescriptions) .

We ate. We drank. A lot.

In less than three weeks, the beef and grease will fly as the Crew descends upon the District for the next installment of our never-ending chronicle of Washington, D.C.'s burger inventory. You better check yo'self, fools, Burger Days VII is going down Saturday, October 5.

D.C. welcomes yet another burger chain into the mix when Smashburger opens its doors in DuPont today at 10 a.m. This is the Denver-based joint's first location in the District and second overall in the Metro area after opening in Fairfax last October.

In late-night-burgering news, we're alerted us to new weekend hours for Shake Shack in DuPont.

While Shake Shack has been making the bellies of the Crew and many others plenty happy, not everyone is thrilled with the N.Y.C. transplant.
