    My order is simple, it’s hard to mess up, so it is up to Dunkin standard in that sense. However, I do not think staff is aware that they work at a train station and that people may be in a rush/ trying to catch a train. Zero sense of urgency from them, ever.

    This is my first one star review on Google. This was a waste of $11. I ordered two signature white chocolate lattes. One had no taste, the other they made ice after I changed my drink order to get a hot latte and when I mentioned that they were obviously annoyed which I understand. However, the replacement drink they gave me was half full and I don’t think was made with an alternative milk. If you need coffee before the train I can’t recommend coming here because I just wasted my own money for bad coffee and pretty poor service
