Very good coffee overall, the use a special Merit coffee bean that is just for them, it can also be purchased there as well. Their brewing process of expresso is excellent and consistent, meaning that I believe they pay attention to PH levels of the water, and you can definitely tell.
Their syrups are made in house, more than likely with real raw cane sugar and not sucrose (which is the white sugar at grocery stores). You can tell the difference between the two, because raw cane sugar is less sweet, and sucrose is super sweet.
Their pastries and foods is all made in house as well, and it is very good. I don't believe that they use Einkorn flour though, I have a gluten intolerance to the bleached flour in grocery stores but not the real Einkorn flour, which is an ancient grain.
