Shake Shack Battery Park City is now open. So for those of you that live and work way downtown and crave that ‘roadside’ burger stand known for its delicious burgers, hot dogs, frozen custard (concretes), beer and wine that Danny Meyer’s knows how to do so well, then head straight to 215 Murray St between West Street and North End Ave and eat. Like all other locations that have concretes inspired by the neighborhood, look out for the ‘Wall-nut Street’ which is vanilla custard, cookie dough, walnuts and Amarena cherries, and ‘Downtown Butter Brown’ with vanilla custard, hazelnut brown butter streusel and seasonal fruit.  www.shakeshack.com
