The leafy awnings of Shake Shack in Madison Square Park haven’t sheltered burger fans for months since closing for renovations in October. But on Wednesday, the chain’s flagship location will reopen with a day-long celebration, new food and an exclusive new beer.

Beginning at 11 a.m. grab a Parkburger (single, $7.09; double, $9.39) exclusively at the Madison Square Park location, topped with raw milk cheese sauce and applewood smoked bacon. For those of you not rushing back to your desks after a suspiciously long break, there’s the new Shack Phoenix brew from Brooklyn Brewery, an unfiltered lager, also only at the park Shack. There will also be entertainment by the Brooklyn United Marching Band and free dog biscuits from Bocce’s Bakery.

And back for Memorial Day weekend at all Shake Shacks (except stadiums, sorry Mets fans) are two seasonal specials: the Shack Corn Dog, made with in-house corn batter and served sweet corn relish ($4.50); and the Red Velvet Cake Concrete ($4.75 or make it a double for $6.75). They’re available Friday to Monday.
