I haven't had a chance to try the cakes, but IMHO, the coffees are very overpriced. I didn't think there was any difference in the taste/quality/portion size, as compared to Barista, Costa or CCD, but the prices are almost double.
I might change my opinion when I try one of the baked goods (on a diet right now) but the cofees, alhough good, are a tad overpriced.
