I suggest Via Napoli where you know the size going in.
There was a recent thread with the breakfast pizza and it was definitely personal this year… with a comparison to last year. That leaves my logic… the pizza window although different owners was last 21 or 22 a pie it then permanently moved to slices only for now 9 or more. It was reported 4 slices is a pie in the past although I can not confirm without buying one and I can tell you the old pie size could be shared by 2 or 3 although more of a lighter meal… I highly doubt you could get a larger pizza at a TS then CS for less but nothing would make me happier to be wrong as I will order the pie to go and enjoy sitting on the BW at night before the fireworks as I did 3 years ago when We stayed at the BW last.
