Oaklandish is a hip (hop) coffeeshop right in front of gate 4. The first thing you notice is a cool street art type mural fronting the shop, stating Oakland is Proud. 
I had wanted to try something local, as chains can be had everywhere else. There is a QR code you can scan and order/pay, in which you just bypass the line and wait for your number to be called. 
As this was my first time here, I opted to wait in line so I could see things a little closer, and ask the person working what they liked. 
They have a wide variety of coffees and teas, the coffee came from what appears to be rotating local purveyors. I ordered a latte which was delicious. 
I was down for just about anything on the menu (think bagels, breakfast sandwiches, toast), and the employee said her favorite thing was the avocado toast. Normally, I don't get too excited about avocado toast, but I took her word for it, and it did not only not disappoint- but it was amazing. The avocado was fresh, sliced not spread, and was dressed with everything but the bagel (like Trader Joe's) sprinkle, lemon oil and micro-greens. I'm still surprised at how good it was. 
Eating in was fun, as the hip-hop music they played was really good, as was the people watching (always interesting at airports). 
Price wise, I read in other reviews the prices were high. As this is the airport, it's higher than it would be in town, but it doesn't bother me. You pay more for everything at the airport. The main thing is the cost performance- which to me was well worth paying for. Good ambience, good quality and testing food, good music- I will 100%. be back again if and when I pass through OAK.
