While a few of the cupcakes (namely the standard flavors) feel a bit overpriced for their quality, many the specialty flavors are fantastic.
Their unique flavors like the East End Stout, Cosmo, or Elvis are really where Dozen's cupcakes become worth the money. As other reviewers have said, the flavors rotate daily, so that can be frustrating if they're serving your favorite flavor on an inconvenient day. On the other hand, it's nice to try and explore all the different flavors this shop sells (but seriously Dozen, sell the Cosmo one everyday). They do sell other baked goods, but the cupcakes are the stars of Dozen.
If you have some money burning a hole in your pocket, these novelty cupcakes might be worth a try.
