Amongst all the hype, Schwartz's was OK.
There was a huge line to the restaurant so we opted for the "take-out" restaurant where you order at the counter and find an available seat. We ordered the smoked meat sandwich and a chicken sandwich and had a side of potato salad. He informed us the chicken sandwich was cold and asked if we would like mustard on our sandwiches.
The sandwiches were small but PACKED with meat. The smoked meat was ok. It tasted just like corn beef. But the chicken sandwich was surprisingly good. It was flavorful - lean but tender. Skip the potato salad, it was very bland.
Side note: there is no lock on their bathroom door. Do go in pairs so someone can watch the door for you.
