Yeah, just stay airside; especially sq likes to board pax as early as possible. Too risky to go to landslide. Lounge food is good; go get cold japanese beer, sake, udon or curry. Sushi restaurant is good too, around $7 a piece. If u keep going straight from the sushi restaurant, you will see food court too. Imho, just stay at the lounge, u wont be dissapointed with the food.
