When I was working on John McGlinn's estate after his death between 2009 and 2011,, we worked out ofd an office space at Park Avenue and 23rd Street. On my walk from there to Toyland at 27th Street and Sixth Avenue, I would pass the Shake Shack and its long line in Madison Square Park. My drummer friend Chris Coluzzi, who worked in the area, claimed they were great.
In 2013, when I would ride the bus down Broadway on my way home from physical therapy, I noticed there was a Shake Shack around 90th Street and Broadway. During the pandemic I ordered food a couple of times from there. The first tie, I really liked it - the shakes are great - but my second time was npt so enthusiastic: burgers tepid, fries okay, and thew shake wonderful. I haven't ordered from them since,
