This is a great simple coffee kiosk in the underground PATH. You wouldn't usually find a little independently run place like this in the PATH, so it's nice to see something different. Their menu is simple and they offer a few sweets if you are in the mood. Based on what I see I think they get them from the same local bakery as many other independent coffee shops that offer quality baked goods.
The service is quick and the baristas authentic looking (A lot of wool caps. It must be cold back there).
My only complaint is they don't offer anything other than brown sugar and 2% milk or 10% cream to put in your coffee (maybe they have it behind the bar?). But, I came for the coffee, not the extras, so SJCB is one of my favourites at the moment - tied with Jimmy's and Thor.
Also, cash only.
