We went to town at SFO. Wife and I have our own cards (they limit it to two people) - so can take kids with. Hit 3 restaurants. Kids like crab and shrimp. So 4 X $28 for each of three restaurants.

But the food wasn't very good. Restaurants in USA are declining rapidly and airport was never very good. Barely edible.

Overall PP is declining with many airports not having any access. I don't see it lasting in its current form much longer. Especially with people hitting multiple restaurants at a time : )
