I flew TN in May, and we liked the new TBIT so much we never made it to the lounge at all, even though all of us had access. We had a drink and snacks at the Petrossian caviar bar, and then met up with friends at the restaurant on the mezzanine level for bigger food and some drinks (service there was slow, but the food and drinks were great)

In PPT there's a large lounge space with drinks and snacks available. There isn't always enough food out, and there aren't quite enough staff to run the front desk and replenish the food fast enough. There were very comfy seats in there though, and it has A/C unlike the cattle herding area at the gate.
