There is a Plaza Premium Lounge on the second floor of the parking garage accessible to Proority Pass, AMEX Plat and Cent and some credit cards. You can also pay for access. No cash taken. Only cards.
It has a good wifi connnection, showers and food and drinks.
Food is an all day menu with sandwiches (hot and cold), and some other apptizers.
I had lunch in the terminal and found this place.
Worked out perfectly !!
