This month is a strange one for BOTMs. One creation isn't even a burger, another is a spin on a burrito dish from New Mexico, and we introduce a new member of the BOTM Club while a charter member teeters on the brink of exclusion.

Burger Tap & Shake

Because throwing pineapple and ham on a burger patty and calling it Hawaiian is lame, BTS gets a standing ovation from the Crew for their take on a Polynesian burger this month. The Book 'em Danno does the beef and grilled pineapple, but rather than lame-o, plain ham, there's crispy-fried Spam plus Swiss cheese and a teriyaki aioli.   2200 Pennsylvania Ave NW | DC | burgertapandshake.com   

Bobby's Burger Palace

This month at the Palace, the Mulberry Street topped with mozzarella, basil ketchup, arugula and Parmesan returns to the scene. We dug last year's version. [Burger Days Review, July 2014]   (On a side note, now that Bobby and the Mrs. are all but done, does Flay keep the Stephanie's All-American in the BOTM rotation? If not, maybe a D.C.-themed burger can get a little play, no?) 2121 K Street, NW | DC | bobbysburgerpalace.com  

BGR The Burger Joint

OK, there is no "B" in this BOTM. In fact, it's not even an "OTM." Because this sandwich from BGR – a Salmon BLT featuring Alaskan wild-caught salmon, Tzatziki sauce, bacon, lettuce and tomato –  is only available until the 17th when it makes way for the seasonal lobster roll (note: also, not a burger) debuting on the 23rd. We may have to seriously reconsider BGR's inclusion in the BOTM Club... 11 Locations in D.C., Maryland and Virginia | bgrtheburgerjoint.com  

Dogwood Tavern

Dogwood goes the homage route this month and breaks out a BOTM inspired by a New Mexican burrito gut bomb. The Travis from Grandma's K & I Diner, a hole-in-the-wall dive in Albuquerque, is a giant beef and been burrito smothered in green and red chili and fries. Dogwood's take on the thing, the Albuquerque Burger, is a ground beef and chorizo burger topped with shoe string fries, cheddar cheese and green chili sauce. Works for us. 132 West Broad Street | Falls Church | dogwoodtavern.com   

Social Burger

And then there were five. This month, we're adding another member to the BOTM Club: Social Burger. The small Vienna joint has just started rolling out monthly burgers and in May, it's the Taco Burger. Extending Cinco de Mayo to a full 31 days, the BOTM has a poblano-and-red-onion seasoned patty with your choice of salsa, pickled red onion, lettuce, tomato and queso fresco.  350 Maple Avenue West | Vienna| mysocialburger.com (We're always on the lookout for BOTMs. If you know of another D.C.-area joint that hooks up a monthly special burger, email us and let us know.)
