You need to know the lunch hours for the restaurant where you want to eat. I called the PS 800# and just asked them to read lunch hours to me for each restaurant I wanted to consider, so that I could include it on the single 8.5 x 11 sheet that I use for reference in my wallet.
Examples:
Concourse Steakhouse lunch runs around 12-2
Teppanyaki Room serves from 12 - 3:45
Le Cellier 12-3
GF Cafe 11:45 - 2:30
Al Fredo 12-4:15
This gave me a lot of scheduling room to consider early lunches for breakfast and late lunches for early dinners.
Teppanyaki room was even nice enough to allow us to use them a little later when our planned reservation was delayed while waiting for a party to join us (they were late arriving from the airport - we were at the restaurant on time).
