There's nothing special about the room at Binion's except knowing it was the home of the WSOP for the first 30+ years. When I was dealt T2, I just had to raise preflop (one of the few hands I actually won).
I didn't make it far enough to find out how tough the competition was, but my table was extremely tight in the early stages. It seemed like no preflop raises were being challenged. In my experience playing online and in California, you will almost never see the entire table fold for one preflop raise, but it happened more than 50% of the time during the 45 minutes I was in this tournament.
Nothing out of the ordinary.
I don't remember seeing a waitress, but again, I wasn't around for long either.
The tournament ran efficiently from what I saw.
There was a prize drawing if you were playing in the live games at some given point after the tournament was over. They withheld a % of the prize pool for this.
