The Unstoppable Shake Shack Wave Will Reportedly Hit the Seaport Next

Massachusetts' first Shake Shack — a New York-based burger-and-shake chain with a cult following — opened a little over two years ago in Chestnut Hill, opening the floodgates to more area outposts. Next came Harvard Square at the end of 2013, followed by Dedham's Legacy Place and Newbury Street in Boston proper in February 2015.

The Seaport District is next, whisper multiple tipsters in the area, one noting that it's slated to open next door to the soon-to-be-completed 101 Seaport building (which is located at 101 Seaport Boulevard). Indeed, corporate filings indicate that Shake Shack has separate LLCs for each of its existing Massachusetts locations — and one called Shake Shack Boston Seaport LLC. While the existence of the LLC doesn't prove that a lease has been signed, it's a good indication that the company is at least seriously eyeing the neighborhood.

Meanwhile, right in the 101 Seaport building, a Chipotle and a Yoki are slated to open, sources say. Yoki, a Japanese restaurant and sushi bar, has an existing location at Station Landing in Medford. It also used to have a location in Cambridge's Central Square, but that one closed in January.

101 Seaport will be anchored by PricewaterhouseCoopers. The building is slated for an October 2015 completion.

Representatives for Shake Shack, Chipotle, and Yoki have not yet responded to requests for comments; this article will be updated as new information becomes available.

UPDATE, 8/13/15 at 10:34 a.m.: Yoki's general manager Phong Nguyen confirms that Yoki will expand to 101 Seaport with a grand opening in April 2016.

UPDATE, 8/18/15: Shake Shack's expansion to the Seaport is confirmed. It's slated to open in 2017 at 85 Seaport Blvd.
