That is the Qr code menu link from the tables. My flights were on Frontier in the A concourse, this is in the B concourse all the way at the far end by Gate 79b next to Starbucks. The gates looked like all UA Express gates. There is seating on one end with a view out of the airport with several UA Express jets and there a section a front of restaurant just looking into the terminal. It was a long walk and I had to take the shuttle train in-between concourses.
You get $28 to spend. If you look at the menu, it's enough for a beer ($10) and an entre ($14 Cheese steak and fries) $3 (soda) which Is what I got. I debated getting cheesecake dessert instead of the beer but figured I've been getting too fat. Could also squeeze in just appetizer and entree with just water or I suppose two entrees. I left a good tip bc it's "free" and I had 4 refills on my Diet Coke. You can leave a tip on credit card even if there is no overage. They out a one cent charge so I could add tip. I made it $7.77 total. I read that a lot of people stuff at these PP restaurants bc they think it's included, don't know they can use credit cards, or whatever reason.
