I bought a couple of cupcakes from here last week, choosing the Nutella and Vanilla on Chocolate flavours.
The vanilla/chocolate combo was passable, I think I would have enjoyed it more sans the white chocolate sprinkles on top. I enjoyed the Nutella one, because it tasted heavily of hazelnut to me and is a flavour I enjoy. However, if you're looking for a rich chocolate-y cupcake with a true, heavy Nutella taste, then you may want to pass on this one.
Overall well-made cupcakes, and I will likely go back to try out a few different flavours. I find that you have to go pretty early on in the day, as there have been a couple of times I've passed this location and they've been sold out of flavours or completely out of cupcakes!
