Is very very good.
One complaint. No concrete Jungle? Are you crazy? The concrete jungle is their best concrete and is extremely popular in NYC.
Yes you can make one from the ingredients but this should be a mainstay on their menu. Plus they are not taking into account all the NYC visitors that will show up clamoring for a concrete jungle and the staff will have no idea what they are talking about, which is highly inefficient.
Other than that I have to say it is a great great burger. When I last had it in ny, they overcooked mine. This one was much better.
