The Cupcakery has pretty darn good cupcakes! In Las Vegas, probably the best, even though I would not say that for other parts of the US.
Some flavors are better than others, and the breakfast 'coffee cake' cupcakes are divine. The frosting is proportional to the cake, which is nice, and the cake is moist and of good quality. I could honestly order just cupcake and no frosting and be perfectly happy about it
The price is something to be desired. $3 - $4 for a single cupcake is a little much, so I save these for extreme special occasions.
