I'm traveling through PSA next week, arriving by at the airport by bus at ≈10:00am and departing PSA-LGW on BA at 12:50pm. I'm hoping to take a quick trip into the city to grab lunch, snap photos of the tower, etc.

1) I understand that there is a Left Luggage service at the info booth for €7 - anyone used it? I have a rollaboard that would be good to ditch.

2) Do I have enough time to get to town and back in 1.5 hrs? What's the easiest/quickest way to get back and forth to the center of town?

3) Any suggestions for good places to eat around there?

I'd appreciate any advice! TIA
