If this Starbucks is too busy for you and you have time between flights, go to the Starbucks around the corner near PZA. It was almost dead in there.
I stood in line for about 20 minutes, which I consider good time since the queue wound its way into the neighbouring store. Got my normal order: venti iced green tea latte with soy milk and an asiago bagel with cream cheese. Only took a few more minutes after ordering to get my lunch. They were fast and friendly and didn't let the stress get to them. :-)
The drink was made almost perfectly. Normally, baristas who have never made this drink just dump matcha powder in the cup, pour in milk, and hope for the best. I always get pockets of bitter matcha through my straw. Not pleasant. This one had barely any clumps. Thanks!!
