I'm an Aussie going to be in NYC in July and being a confirmed foodie I will be in search of the best Reuben sandwich in NYC. (also in search of the best bagel and the best Philly cheese steak but know I may have to go to Philly for this last one!). Any locals or insiders who can steer me in the right direction? I will be staying in Chelsea, but am willing to travel to find the best!!
