I tend to prefer this Starbucks when I'm in a bit of a rush because I've found the workers tend to be faster yet careful in making drinks. Plus the close alternative is the Starbucks on Fifth and ALL of the PITT students go there ... Having the mobile app helps a lot! Especially if you frequent pretty often, like me.
But if you're looking for a place to sit, good luck! The interior isn't as well-lit as I would have hoped it to be but I think it's the fault of the location, if anything.
For non-coffee drinks, I tend to get the strawberry açaí refresher when I'm in need of something refreshing and light. I get the hot matcha green tea latte when it's cold out. The jade citrus mint tea with honey is good for a sore throat! If you bring your own cup, you get a few cents discounted.
For coffee drinks, I get the lattes sometimes with a pump or two of syrup. Take advantage of the customizations you can make! I've fallen in love with the blonde roast, personally. Try it out!
