I went to Davios with my Priority Pass tonight, then stopped by the Chase lounge after. If you want a full meal, go to Davios and be prepared to spend $10 over your $28 Priority Pass allowance before tip. The meal at Davios was really good but was definitely a lot of calories.
The Sapphire lounge was packed at 5 pm tonight, uncomfortably so. The drinks were quite good and still arrived promptly. I would choose Davios over the Sapphire Lounge for a meal, and the Sapphire Lounge for a drink and a light bite.
