Hi Dan, I think we got there around 11:10 or so...I remember lurking here back when I did it and the advice was to get there pretty early. I don't know how necessary it was having the first seating ressies of the day, but I wanted to be sure. I'll tell you one thing, there were people that had checked in ahead of me, and the line to make reservations day-of was astounding, much like the line USED to be years ago before they took PSs (I had to stand in that line with my Grandma who "forced" me to eat there on a trip when I was oh, about nine, but once I had a Monte Cristo I never looked back of course)....the people there were all dumbfounded and disappointed that they couldn't get in...lots of folks who knew the old system. It's too bad, really, a lot of people were making reservations for later in the week, but for folks that waited until their last day or whatever were really bummed.
We ended up sitting on the step to the restaurant since all the benches were taken and I was so nervous, and then of course we were called in after the first three or four parties and got a perfect seat on the edge of the water. I agree with all others, if you aren't on the water it's just a dark restaurant.
Have a great time!! Good luck getting your PS!
