Escape lounge at Oakland Airport was very quiet and pleasant - I literally used it for just 10 minutes to check it out before a flight to LA. Bar looked well stocked and food items looked decent. Lounge was not packed. WiFi was decent, about 30mbps (though I have to note that I was just in Korea which had ridiculously fast gigabit WiFi in many places, so it’s all relative.) No bathrooms but plenty of nice spots to sit, outlets, tables, couches. I just had some tea (which was quite good!) Overall worth it even for just those ten minutes!
Flew in to Burbank though which is really dingy. I hope they replace that tired airport soon.
