Went here the morning after a long night of drinking and boy did it hit the spot.  Got there around lunch time and the line for the restaurant section was out the door and down the block.  Me and my guys opted for the to-go side and even there we had quite a bit of a wait.  After ordering an enormous amount of pastrami and some sides we got lucky and found an area to eat in the back.  Let me say that it was the best pastrami sandwich I had every had.  This coming from a New Yorker who enjoys Katz.  I thoroughly enjoyed every bite of that sandwich and the only bad thing is that I can't have this unless I am up in the great white north.
